Thanks Bonnie. That one indicates a normal cat is wider when you look
down on them than the chart in my vets office, but it did say that a
very thin or ematiated cat will have ribs and hip bones clearly felt,
and luckily Shamrock's bones aren't sticking out or anything. I've
been watching his food intake carefully and he's eating ok. He's due
for a checkup for bloodwork for the medication he's on, so I'll see
what he weighs and discuss my worries with the vet.
