I have no idea what is/was wrong with the cat, but he *seems* to be on the mend, somewhat. I ended up getting a pill popper syringe from the vet to give him his one drug and that is working. The other drug — an antiobiotic is in liquid form which I can easily give him. He’s starting to eat and drink … at least a little again. He’s lost weight, so he’s skinny, but slowly he seems to be bouncing back. Phew.
