You’ve probably seen squirrels poking around outdoor bowls or grabbing pet food left outside. Squirrels eat cat food because it’s loaded with fat and protein, and honestly, they’ll take any easy calories they can find—especially when natural food runs short.
Feeding squirrels cat food all the time can mess with their health and behavior, so it’s best not to offer it as a regular snack.
If you want to help wildlife without causing issues, you’ll need to know which foods are actually good for squirrels. Keeping pet food safe from wild visitors matters, too.
Let’s talk about why squirrels like cat food, what health risks come with it, and what you can do in your yard instead.
Will Squirrels Eat Cat Food?
Squirrels don’t hesitate to grab cat food when they find it. They go for the smell, the texture, and the convenience, not because it matches what they’d eat in the wild.
Why Squirrels Are Attracted to Cat Food
Squirrels love both dry and wet cat food, mostly because of the strong animal-protein scent and all that fat. Those smells really stand out in a yard and make squirrels hungry fast.
If you leave a bowl outside, the scent travels and can lure squirrels from trees, fences, or even rooftops.
Cat food gives them a quick, effortless calorie boost. Searching for nuts or seeds takes work, but a dish of kibble or canned food is just sitting there, ready to eat.
Feed your pets outside? Squirrels will figure out the routine and keep coming back.
Opportunistic Feeding Behavior
Squirrels eat whatever’s around and seems safe. Usually, that means seeds, nuts, fruit, and sometimes insects.
If pet food shows up, they treat it like any other easy meal and jump at the chance.
You might notice them raiding pet bowls, trash cans, or bird feeders. Once one squirrel finds cat food, others catch on fast.
How Often Squirrels Eat Cat Food
How often squirrels show up depends on what else they can find and the season. In fall and early winter, they focus on storing natural foods and might ignore pet food more.
When spring or late summer rolls around and natural food isn’t as plentiful, squirrels check out pet bowls more often.
If you leave pet food outside all the time, expect daily or even nightly visits. One feeding spot can turn into a regular stop for them.
Want fewer squirrel visits? Feed pets indoors or take away leftovers right after your pet eats.
Differences Between Wet and Dry Cat Food
Dry cat food (kibble) appeals to squirrels because it’s easy to grab and stash. They can carry pieces in their cheeks and hide them in tree holes or under leaves.
Kibble also lasts longer outside than wet food.
Wet cat food smells even stronger and has more moisture, so squirrels will eat it if there’s no dry food. But it spoils fast and attracts other pests like raccoons or bugs.
If you must feed pets outside, dry food makes less of a mess, but it still draws squirrels. Wet food just brings more visitors and can cause sanitation problems.
Risks and Health Concerns of Feeding Squirrels Cat Food
Giving squirrels cat food can mess with their nutrition, put stress on their organs, and even change how they act. You might also end up attracting other animals and creating a mess near your home.
Nutritional Needs of Squirrels vs. Cat Food
Squirrels need diets full of plant fats, fiber, vitamins, and the right minerals. They eat nuts, seeds, fruits, veggies, and a few bugs.
Their bodies rely on more vitamin C, a different balance of calcium and phosphorus, and plant-based fats—stuff cat food just doesn’t provide.
Cat food is for obligate carnivores, so it’s packed with animal protein, fats, taurine, and preservatives. Squirrels can miss out on key nutrients or get too much protein and phosphorus.
Over time, that mismatch can lead to bone problems, immune issues, or metabolic trouble.
If you want to feed wildlife, try unsalted nuts, squirrel-friendly seed mixes, or fresh fruit instead of processed cat food.
Potential Health Problems for Squirrels
Cat food’s high protein and certain minerals can strain a squirrel’s kidneys and liver, especially in young or old squirrels.
Too much fat can cause obesity and fatty liver. Additives and preservatives might upset their digestion and harm their gut.
Lack of vitamin C or the right calcium can leave them with weak bones, a scruffy coat, or a weaker immune system.
If you notice squirrels acting tired, gaining weight, having diarrhea, or behaving oddly, stop feeding cat food and reach out to a wildlife rehabilitator.
Behavioral Changes in Squirrels
Feeding cat food can make squirrels rely on handouts instead of searching for food. They might show up at the same spot every day, waiting for more.
This dependence means they spend less time foraging and hiding food.
Squirrels get bolder when they expect food from people. They might approach yards more often and lose that natural caution.
That can lead to bites, property damage, or neighbor complaints.
You can help by offering the right foods, keeping feeding limited, and setting up feeders that encourage natural foraging.
Attracting Unwanted Wildlife and Managing Feeders
Cat food doesn’t just interest squirrels. Raccoons, rats, opossums, feral cats, and even some birds seem to love processed pet food too.
That kind of buffet can boost disease spread and draw more predators right up to your door. It’s a hassle nobody wants.
Try using secure, squirrel-proof feeders. Don’t leave food out overnight if you can help it.
If you really want to feed, go for squirrel-specific mixes or just a few whole, unsalted nuts. Keep portions small.
Make it a habit to clean feeding spots often. Mold and rodents show up fast if you don’t.
When wildlife starts causing trouble, stop feeding altogether and get rid of leftover food. Reach out to local animal control or a wildlife rehabilitator if you need advice on keeping animals away or moving your feeders.
