Re: VITAMIN D QUESTION
Lots of non release squirrels live indoors without UV lights and don't come down with MBD let alone twice.
Something else is wrong here. Just my opinion. Diet is always key.
You're giving squirrel blocks.
Check to make sure he is actually eating them and not hoarding them around the house.
Our non release have done this and I've read about plenty of others doing so.
I would suggest giving the blocks before you give them any other food. Once they eat those they can get other things.
If I give blocks with a plate full of other things they won't touch the block. If they aren't eating them it does not matter if you give them.
There are other foods which can be used as their staple nutrition for variety as well. Rodent blocks, Henry's squirrel blocks, Boo Balls, Zupreme Parrot, etc.
