He was staring at my little dog !

This is a male, correct? And can anyone tell me what are the spots on its face? Thank you!

2 months ago I had two squirrels occupying this tree. One was big and the other a bit smaller in size. The big one would always chase the smaller one all around and up and down the tree.

Now those two squirrels are gone and these two much smaller ones have just recently been occupying the same tree, with no squirrels chasing them around.

Almost like it's, "OK, your turn to live there, enjoy"

We got a squirrel that my brother found on Sunday. Was found by his daughter, I didn't ask and I assume trying to reunite the baby with his mother didn't happen. She found him away from the house and brought home.

Initially though he was older, tried to feed him nuts being kinda novices we finally got goats milk powered formula meant for puppies. This is what was recommended to us. With formula they are consuming about 4.5ml per feeding about 5 or 6 times per day.

Also providing warmth for them, I wasn't sure but noticed after the first couple hours he was surely cold. Not being able to correctly determine age I was unsure what they required.

How am I doing so far? Lol bad picture but I'll try to post more later. Outside of feeding they really aren't active much. I do try to stimulate them after feeding but seems they don't quite need it but has caused them to relieve themselves a few times so I do it after every feeding.

Only one, probably not a healthy choice for her .

I saw a couple drops of pink urine at the spot where I give food and water to my wild squirrel friend. Very concerned that it's because of something I fed him.

I give him about two treats a day, usually a Henry's block, blueberries, or nuts. Often I put small pinches of calcium on the nuts and berries. I wanted to avoid giving him any calcium imbalance, but now I worry the calcium was needless overkill and I've given him kidney stones.

Any tips on what I should do? I plan to ditch the calcium and keep water available. For now, his behavior seems totally normal. Since he's a wild I am hesitant about taking him to a vet because I don't want to traumatize him, but I'm certainly open to it.

And their relatives, too, like marmots. I read that in captivity, squirrels can live up to 20 years. Wild European hamsters also can hibernate, but still only live a few years. Squirrels also have a high metabolism relative to their size, so this surprised me.

Title.
I don't want to accidentally leave out something that might be bad for the squirrel, I just want some ok footage of one burying one. Is there one particular nut they'll be likely to bury?
