My 10 week old Cosmo has been with us for a week now. He is still adjusting to his new home, hasn't been eating as much as he should according to our vet. He won't eat out of the bowl, I have to feed him from my hand or place the kibble on the floor then he plays with it and eats slowly one by one. A suggestion from our vet was to break up one of his favorite treats (liver bites) in the kibble. It worked great, he eat the entire bowl in a matter of minutes, then slurped down all of his water. As he walked away his sides were bulging, he looks like a balloon! He kind of burped and is still going to the bathroom 1 and 2. Is this from swallowing too much air and/or swelling kibble?
