I wouldn't worry about the feedings either. I still offer warm almond milk to Truely and sometimes she's wants it and sometimes she doesn't but it makes her feel loved that I offer. I think this is one of the most important things you can do for your Too. Also he is getting the extra nutrition and calories he needs to keep on getting better. I have to say you are a wonderful Mommy, I've read about the sacrifices you and your family made so that Ozzie could get to the vet. Big hugs to you.
