I've had my male eastern gray squirrel, Samuel, for a year next month. Starting this past spring he began showing signs of balding on his tummy and now it's begun to spread to his legs as well and he's visibly scratching a lot more. There are no sores and the skin doesn't look irritated. I've checked him repeatedly for any kind of infestation or obvious irritant and never find anything. We had one incident in June when he was running through the apt and started making a gagging noise and there was a bit of foam around his mouth. Never happened before that or after. I came to the conclusion that his light was at its 6 month mark and perhaps that was a reaction to him not being able to properly metabolize his calcium.
I've tried to be very cautious with his nutrition since I rescued him from a feral cat when he was estimated to be about 5 weeks of age. He received Esbilac puppy formula mixed with heavy whipping cream until he was eventually weaned to a regular diet of avocado, bell peppers, mixed greens, sweet potato, butternut squash, radishes, sugar snaps, green beans, carrots, tomatoes, mushrooms, the occasional squirrel approved fruits...and much more. On top of that I order squirrel nut bars from the squirrel nutrition man as well as calcium hearts. He's got a UVB light that is replaced every 6 months because I live in an apartment in the city and can't take him outside safely for the time being. Next summer I'll be moving to a house with a yard where I'll make him an outdoor enclosure.
From my research I started offering him raw coconut which he'll eat at first but then won't touch his food for that day and sometimes the next so I worried it was not agreeing with his stomach. I also started rubbing coconut oil into his skin, he is not happy about this. He gets mixed nuts in the shell that I've recently cut back on. He appears to be a healthy weight considering some of the rather fat domestic squirrels I've come across on the Web. I've also recently moved him from his first cage which was wooden to an all metal "bird" cage. There were no issues the last two weeks but a few days ago he started refusing to go to the bottom and acts very alert and cautious if I try to tempt him down there with treats. His behavior overall has become a little more "stiff" and not the norm these last few days. He just turned 1 year this month and don't know if that has anything to do with it.
I have considered he may just be shedding but I need some reassurance, especially with his odd new behavior. I forever stress that he will get MBD despite my best efforts. Any insight would be much appreciated. Thank you for taking the time to read this!
