Stop in for a cup of coffee
The insurance isn't cheap but it does help. Vet we use it seems like every time they have to do blood work.
One thing I learned over the years cats are usually lethargic after surgery, and won't eat.
Vet gives mine Valium he said its like pot for cats gives them the munchies. I laughed first time he did it to one of the cats. His face was just buried in the bowl. He was so stoned he couldnt raise his head.
