Squirrels spend huge amounts of time each day foraging for food. So what are they looking for? Squirrels eat nuts (especially acorns), seeds, flowers, fruit, buds, fungi, and sometimes even insects and baby birds.1,2 If you’ve ever seen a squirrel going through the trash, then you know they love to eat human food as well!
Of course, squirrels don’t eat the same foods all the time. Their diet depends on what’s available during each season. For example, squirrels eat buds in the spring when plants are developing new leaves and flowers and then fruit in the summer when it appears.2
A Quick Guide to Squirrel Nutrition
If you have a pet squirrel, you may be wondering how much of each type of food to feed your furry friend. Fortunately, a healthy and balanced squirrel diet is extremely easy to achieve. Nuts and seeds make up as much as 95% of the eastern gray squirrel diet.3 In particular, squirrels prefer acorns, hickory nuts, and beech-nuts.1,4 Insects and other food derived from animals make up under 2% of a squirrel’s diet.2
To prevent your pet squirrel from eating too much or too little, we should also figure out the total amount of food he or she needs every day. Let’s start with the fact that the average squirrel eats about 100 pounds of food each year.2 Some simple math will give us our answer:
So, your squirrel will need just over a quarter pound of food every day.
What About Baby Squirrels?
Like other young mammals, baby squirrels drink milk from their mothers. Squirrels nurse their young for about 3 months, which is a long time by rodent standards.5 Every mammal produces its own unique type of milk, and squirrels are no exception. Compared to cow milk, gray squirrel milk has less water and sugar but more protein and fat.6
If you’re raising a baby squirrel, you can make your own squirrel milk using this recipe.

I rescued Rocky from a cat when he was about 3 weeks old, his eyes and ears were not open. I did leave him alone (but watched closely) for several hours in hopes his mother would find him, she did not. So being the animal lover that I am and I have rescued squirrels in the past but was able to release due to their age at time of rescue, I brought him in, feeding and attending to him every few hours. Because of his age and human contact I still have 8 month old Rocky, he has a 4 story custom made condo and every day I bring him out to run my large porch and give him attention he graves. He is a special little creature.
Can you post a photo of his condo?
Yes I would you to see pictures also. Thank you.
