As you can see, even though they are very young (eyes still closed but not newborns as they have hair even though the tail is 'skinny')m they are also quite big in size but that's because adult grey squirrels are biggish creatures (they can weigh up to 1.5 lb). And their little feet allow them to stick like Velcro to vertical surfaces
And, yes, they are the cutest things!!! And so very cuddly! Put them down and they immediately start crawling, looking for a warm body - put your hand in front of their face and they burrow into your palm curling themselves into a little ball (the grandson I care for in the afternoons warms up his hand so he can do it and goes AWWWWW AWWWWW AWWWWW the whole time he is doing it
).
I had to go through a bit of a learning curve figuring out how to feed them, how much and how often but with a bit of experimentation, I found the right way and they are now doing great (good appetite, nicely hydrated, active, etc). I do worry about releasing them though. I don't live, like you did, Liz, in an 'animal friendly' area so I can't just put them out during the day (lots of feral cats, dogs that are let out in the backyards and, unfortunately, also some bad people). Add to this my crazy dogs that run like maniacs after anything that moves and which go out 6 or 7 times a day, and the feral cats that prowl my backyard constantly because there is always food for them and I don't know how I am going to manage putting them out there and ensuring their safety... but we will cross that bridge when we get to it.
