Outdoor cats face a unique set of challenges when it comes to staying warm through frigid winters. Unlike their indoor counterparts, outdoor cats cannot simply snuggle under a blanket or bask in the warmth of a heated home. Instead, they must rely on specialized adaptations and behaviors to maintain a healthy body temperature when temperatures plummet. With some clever tricks and proper preparation, outdoor cat owners can help their furry friends stay cozy all season long.
Finding Shelter from the Elements
One of the most important ways outdoor cats stay warm is by finding shelter that protects them from wind, rain, snow, and cold temperatures. Ideal shelters for outdoor cats include:
Barns, Sheds, and Outbuildings
Barns, sheds, garages, and other outbuildings can provide excellent refuge from winter weather if the cats can access the interior. These structures block wind and precipitation and often provide at least marginal insulation. Outdoor cats may hunker down in barns packed with hay that retains heat and provides burrowing opportunities. Just be sure any vehicles or machinery inside won’t harm them.
Hollow Logs or Trees
Hollow trees, logs, and stumps offer an insulated spot protected from moisture and wind. Outdoor cats often sleep inside fallen hollow trees or excavate burrows under tree roots. Pile brush over the entrance to further barricade drafts.
Porches, Decks, and Crawlspaces
The space under porches, decks, and elevated structures can shelter cats from the elements. Clear storage items to create open areas for cats to nestle beneath. Just be sure the space stays dry and will not flood during snow melts or heavy rain.
Insulated Shelters
Commercially available insulated outdoor cat shelters or homemade shelters made of insulating materials like straw can create a warm refuge. Place the shelter in a protected area and ensure it stays dry inside. Bed with straw or blankets.
Dens and Burrows
Leaf piles, brush piles, and debris can facilitate den creation for added warmth. Outdoor cats often burrow into soil or piles of vegetation like straw to create an insulated nest. Encourage this natural behavior by providing material they can burrow into.
Vehicles and Machinery
Cats sometimes crawl underneath parked vehicles, machinery, or equipment. This gets them up off cold ground and can block wind. But be sure to tap on hoods or honk horns before starting engines to avoid harming them.
Inside Access
If possible, allowing outdoor cats limited access to the indoors provides opportunity to warm up. Install a pet door or occasionally let them inside during the worst weather for short periods.
Growing a Winter Coat
To produce crucial insulation against winter’s cold, outdoor cats develop two types of hair: long, coarse guard hairs and a soft undercoat. The two layers work together to trap body heat close to the skin.
Guard Hairs
The long, coarse outer hairs, called guard hairs, form a water-resistant barrier shielding the cat’s skin from snow and rain. This protects the insulating undercoat to keep it dry and fluffed.
Undercoat
Under the guard hairs lies the undercoat – a layer of fine, downy hair that grows denser in winter. The undercoat prevents body heat from escaping and keeps the cat warm. Regular grooming fluffs it up to optimize insulation.
Seasonal Differences
Summer coats shed out the dense undercoat, leaving just the guard hairs to stay cool. But as daylight hours decrease in winter, cats begin growing their heavy undercoat for added warmth. This winter coat sheds out again come spring.
Grooming
Outdoor cats put effort into licking and grooming their coats to fluff the fur for better insulation. Matted, wet fur loses insulating abilities. Brushing cats during their winter sheds can help remove loose hair and separated the hairs.
Nutrition
Getting adequate nutrition ensures cats have the energy reserves to grow thick, healthy coats. Feed outdoor cats a nutritious diet rich in omega fatty acids for skin and coat health. This equips their bodies to develop the best winter coat.
Conserving Body Heat
Beyond just having a well-insulated coat, outdoor cats also use specialized behaviors to conserve precious body heat in cold conditions. Knowing these tricks can help owners support their natural winter adaptations.
Seeking Heat Sources
Outdoor cats tend to sleep and rest against warm surfaces when available. They may soak up heat from sun-warmed walls and sidewalks on sunny winter days or cuddle up near the warm exhaust ofrecently shut off vehicles. Providing insulated shelters captures their heat-seeking behaviors.
Tucking Limbs Close
Cats conserve body heat by tucking their limbs close against their bodies rather than extending them. Outdoor cats may tightly tuck their legs and paws underneath them or beneath their bodies when sitting or sleeping in cold temperatures. This reduces surface area and keeps heat centered near vital organs.
Curled Sleeping Position
The tightly curled up sleeping position also supports heat retention in cold weather by minimizing exposed surface area. Outdoor cats may ball themselves into tight, compact spheres or sleep curled tightly into piles with other cats. Their tail usually covers their face and extremities for added insulation.
Muscle Tremors
Cats may shiver or experience muscle tremors to generate heat when feeling chilled. The involuntary muscle movements raise their metabolic rate to produce more internal body heat. Outdoor cats conserve energy by restricting shivering only to periods when they cannot find other ways to stay warm.
Piloerection
Piloerection occurs when a cat’s hairs stand on end, often called “fur standing up.” This fluffs out their coat to create more trapped air and maximizes insulation. It also increases the cats visual size as a defense against threats. Noticeable piloerection signals a cat may not be warm enough.
Vasoconstriction
By constricting blood vessels in their extremities when chilled, cats can prevent body heat from escaping through their paws and ears. Outdoor cats may have cool ears and paws even with a warm core body temperature due to vasoconstriction.
Sunbathing
Outdoor cats sunbathe on sunny winter days to soak up radiant heat from the sun’s rays. This raises their body temperature and facilitates vitamin D production. Providing cats a sunny resting spot works with their natural sunbathing habits.
Nutrition for Cold Weather
Proper nutrition provides outdoor cats with the energy required to keep warm when temperatures drop. Target their diet to equip their bodies for winter’s energy demands.
High-Calorie Food
The more calories a cat eats, the more energy they have to burn for body heat production. Feed outdoor cats energy-dense foods or increase portion sizes in winter. Kittens and older cats need extra calories.
Frequent Small Meals
Small, frequent meals keep a constant supply of energy available for cats. Their bodies work hard simply staying warm in frigid conditions. Free-choice dry food access allows cats to eat small meals through the day.
Water
Dehydration forces the body to work harder regulating temperature. Ensure outdoor water sources don’t freeze entirely so cats stay hydrated. Use heated bowls or refresh frequently. Canned food adds moisture too.
Fatty Acids
Omega-3 and omega-6 fatty acids support skin and coat health for proper insulation. Choose cat foods containing fish, vegetable oils, and other natural sources of fatty acids – or give cats oil supplements.
Protein
Outdoor cats use protein as fuel to generate body heat. Choose a high-protein cat food or feed extra meat, eggs, or other protein sources in winter. Kittens and cats recovering from illness need more protein.
Other Winter Considerations
Beyond the major points already covered, some additional considerations can help owners keep outdoor cats warm through the coldest months.
Shelter Maintenance
Regularly check outdoor shelters for signs of cold air or moisture getting in. Make any necessary repairs promptly to keep the enclosure insulated against drafts, rain, and snow. Ensure the floor stays dry.
Nesting Bedding
Provide warm, dry bedding like straw, blankets, towels, or even sheets in outdoor cat shelters. Avoid fabric that could get wet or retain moisture. Swap out bedding at least weekly to keep it fresh.
Outdoor Water Access
Use heated cat water bowls, refresh water frequently, or provide water access in shelters to prevent freezing. Dehydration makes regulating body temperature much more difficult. Snowmelt or thawed frozen food can supply moisture as well.
Toxic Chemicals
Antifreeze and other winter chemicals are toxic. Use pet-safe ice melts, ensure vehicles aren’t leaking, and keep chemicals out of reach. Avoid salt licks which can cause gastrointestinal upset in cats if overconsumed.
Winter Pet Care Limitations
Grooming, nail trims, teeth brushing, bathing, and other routine care become less safe and critical for outdoor cats in frigid weather when the goal is preserving body heat. Revisit these in spring when winter coats shed out.
Watch for Frostbite
Ears, tails, paws, and other extremities are vulnerable to frostbite in bitter conditions. Bring cats inside immediately and gently warm affected areas if you suspect frostbite – indicated by pale, icy skin. Avoid rubbing the area. Get veterinary care.
Outdoor Feeding Stations
When free feeding dry food outside, use tip-proof bowls. Choose lightweight metal bowls that won’t crack in frigid temperatures. Place bowls in sheltered areas protected from wind and snowdrifts. Monitor food amounts and remove uneaten portions.
Emergency Winter Shelters
Have an emergency source of shelter ready in case you need to suddenly bring outdoor cats inside due to impending storms, rapid temperature drops, or other hazardous conditions. A garage, mudroom, or bathroom can provide temporary refuge.
Outdoor Cat Health Concerns
Get cats checked for common winter illnesses like upper respiratory infections before cold and flu season starts. Watch for limping, pain, or other signs of arthritis flare ups. The elderly and chronically ill need close monitoring in severe weather.
Clothing and Booties?
Cat clothing like coats and booties usually do more harm than good. They can stress cats, irritate the skin, and interfere with body heat retention. Well-fed healthy cats with proper shelters rarely need clothing even in harsh climates.
Frequently Asked Questions
How do outdoor cats keep warm in the winter without blankets?
Outdoor cats stay warm by growing a dense winter coat, conserving body heat through posture and activity, seeking warm shelters, generating heat through shivering and cat huddling, eating extra calories, and soaking up heat from the sun whenever possible.
What is the best shelter for outdoor cats in winter?
The best outdoor winter shelter has a waterproof roof, insulated walls, ample bedding, and a raised floor away from cold ground. It contains stored body heat while blocking wind, rain, and snow. Barns, sheds, hollow logs, and insulated DIY shelters all work well. Ensure cats can come and go freely.
Do outdoor cats need pet coats or booties for the snow?
Healthy outdoor cats typically don’t need any clothing like coats or booties to stay warm. Their winter coat provides sufficient insulation. Clothing usually interferes with cats’ natural ability to conserve heat. Only very elderly, arthritic, or sick cats may benefit from a coat when briefly outside.
What food helps outdoor cats stay warm in winter?
High protein, energy-dense cat foods with extra calories from protein and fat help fuel cats’ metabolisms to produce body heat. Omega fatty acids from fish, eggs, or oils give healthy skin and coats. Avoid dehydration by providing accessible water. Small frequent meals keep energy levels steady.
How can I provide water to outdoor cats in the winter if bowls freeze?
Use tip-proof heated water bowls, refresh water multiple times daily, provide water in shelters/outbuildings so it doesn’t freeze, offer canned food for moisture, and check for snowmelt puddles outdoors. Cats won’t survive without proper hydration in winter.
Why do outdoor cats shiver or tremble?
Muscle tremors or shivering generate heat to warm up cats when they feel chilled. Outdoor cats restrict this only when necessary to conserve energy. Shivering indicates a cat may be having difficulty staying warm enough and needs access to better shelter or heat sources.
Do cats prefer heat or blankets for warmth in winter?
Given the choice, most cats prefer basking on warm, sun-heated surfaces rather than curling up under blankets. Their coats already insulate them from cold if kept dry. Outdoor winter cat shelters should take advantage of captured solar heat, not just provide blankets which can become wet and cold.
How can I warm up a cold cat after being outside all night?
Start by bringing the cat indoors into a warm room away from drafts. Swaddle them in a dry towel straight from the dryer. Place reusable hand warmers under the towel near their limbs and torso. Offer a normal-temperature meal once their body warms up to avoid shocking their system.
Why do cats grow winter coats and then shed them again in spring?
Outdoor cats shed their heavy winter undercoat once daylight hours increase and temperatures warm up in the spring. The shedding drops their dense insulation so they don’t overheat as summer approaches. Their summer coat consists of just guard hairs to stay cooler in the heat while blocking sun exposure.
The Takeaway
Outdoor cats are remarkably resilient when it comes to contending with winter’s freezing temperatures and storm conditions. By growing specialized insulating fur, modifying behaviors to conserve heat, and taking advantage of outdoor shelters or heat sources, most cats can thrive through cold seasons. Owners can support natural winter adaptations by providing nutritious food, accessible unfrozen water, and warm, protected structures cats can retreat to when the weather takes a bitter turn. With preparation, knowledge of their abilities, and attentive care, outdoor cat owners can ensure their beloved felines stay happy and healthy all winter long.
To summarize how outdoor cats stay warm:
- They grow thick winter undercoats beneath longer guard hairs for insulation.
