I'm staying with a friend and his cat is very sick. The kitty is going to the vet first thing in the morning, but until then, we're wondering what we could possibly do to make him more comfortable. Unfortunately it's just not possible for us to take him to the vet now with it being Sunday evening and all.
The cat is very lethargic, has labored shallow breathing. He's very weak, and from time to time starts crying. He won't eat or drink. He can't really do much more than lay around, and even that seems to be quite painful for him.
Is there anything we can do for him until he can be seen at the vet?
