Feeding a stray or community cat? Here's what it needs besides food this winter

You started with a bowl

It usually begins small. A cat shows up by the back steps, you put out some food, and a few weeks later it's waiting for you every evening. Animal welfare groups call these community cats: stray or feral cats that live outdoors, often near the people who feed them.

Food matters even more in winter. Cornell's Feline Health Center notes that cats burn more calories to stay warm and should be fed somewhat more. Alley Cat Allies recommends larger portions and wet food, which "takes the least amount of energy to digest." But for a cat that sleeps outside every night, food is only half the picture.

Why shelter matters as much as food

A cat that can't get out of the wind and wet loses heat fast. Cornell names "the combination of low temperatures, wind, and snow/ice" as what puts cats at risk of hypothermia and frostbite. PetMD's veterinary guidance treats temperatures below 32 °F as dangerous for all cats with prolonged exposure.

Many community cats find a spot under a porch, a deck or a parked car. Those places are not always safe. That's why Alley Cat Allies and the AVMA both advise checking under your car and banging on the hood before you start the engine.

What a good shelter looks like, according to the people who build them

Groups that work with community cats every day agree on most of the basics:

• Size. Small enough to hold heat. Alley Cat Allies: "Larger shelters are not necessarily better, since heat disperses quickly, leaving the inside as cold as the outside."
• Doorway. "No bigger than six to eight inches wide to keep out predators and other animals," with a flap against snow, rain and wind (Alley Cat Allies). Neighborhood Cats uses doorways of about six inches.
• Raised. Off the ground, to stay drier and keep body heat from draining into the soil (Cornell, Alley Cat Allies).
• Bedding. For unheated shelters, straw, not hay, blankets or towels. Neighborhood Cats explains that blankets pull heat away from a cat lying on them, and hay can grow mold.
• Location. Quiet and away from foot traffic (Alley Cat Allies), weighed down or anchored so wind can't move it (Best Friends, Neighborhood Cats).

Getting a wary cat to move in

Community cats are cautious, and a new box in their territory can take a while to accept. Two tips from the groups above:

• Catnip. Neighborhood Cats and Best Friends both suggest sprinkling some catnip inside at first.
• Open first, flap later. Neighborhood Cats suggests adding a door flap once the cats are using the shelter. If your shelter's flap can be rolled up or fastened open, start that way.

Give it time, and set it up where the cat already spends time.

If there's a power outlet nearby

A heated pad keeps a shelter warm even when a cat is alone or the night is long. Best Friends Animal Society notes you can "provide an electric heating pad to create a heated cat shelter" and stresses using "a heating pad made specifically for pets." An outlet also lets you use a heated water bowl, which Alley Cat Allies and Petfinder recommend to keep water from freezing.

That's where Comfort Zone comes in. It's a compact grey Oxford-fabric shelter on a metal stand, with a waterproof heating pad on the floor and two ground stakes. Two exits with clear PVC flaps mean a cautious cat can see out and is never trapped with only one way out.

The power cord exits under a flap with a cord cover. Route it along a wall or fence, plug into an outdoor-rated GFCI outlet, keep the connection dry, and check the cord regularly.

Beyond the shelter

• Trap-Neuter-Return (TNR). If the cat you're feeding isn't spayed or neutered, a local TNR group can often help. Alley Cat Allies has resources to find one.
• Friendly and maybe lost? A cat that approaches people may belong to someone. A local shelter or vet can scan for a microchip.
• On the most extreme nights, no outdoor shelter replaces a warm indoor space. If you can offer a garage, mudroom or carrier inside, the guidance from PetMD and the AVMA points that way.
