In The Sims 4: Cats and Dogs expansion pack, you can feed a live squirrel to an owl by selecting the "Feed Owl" interaction on the squirrel in your Sim's inventory. This will allow the owl to eat the squirrel.
Feed them pecans

you could buy some bread and squirrel feed for them like little seeds maybe even bigger nuts like pecans etc.
yes, as it is unlawful to feed any wild animal in Florida
No because if it can not move it will not be able to feed itself.

i will not tell you because you may not feed that baby squirrel the food i was about to give . ask a vet . ask its mother . but do not ask me . i am not a squirrel expert . neither is my dog . she eats them .
It seems to me that they can do it. However, have a chat with a vet about.
Other frogs, fish, birds, turtles and large insects will gladly feed on Hyla squirella.
The cat milk will not have all the nutrients, or enough of the nutrients that the squirrel requires. I'm no expert and i don't think it will hurt the squirrel but it would be better if the baby squirrel could have its mother instead. or course if the mother is out of the option you could always talk to a vet or wildlife management; there should also be plenty of info on the web about it; but don't feed it processed milk. if the cat will let the squirrel nurse then go ahead and let it be but look for other options because there may be something in the cat milk that would be detrimental the the baby squirrels health.
