One way or another, they will get you. One of my fat kitties started losing weight dramatically, so I took him to the vet -this is an oversimplified statement, given that such task requires hunting down above mentioned feline for hours and finally, using a net to get him in the pet carrier. Seems he's got a tumor and and infection. So he is residing at the hospital at the moment. How do I know he is doing better, though? Well, since he started receiving medication, there is bloody murder in his eyes. The vet is also using the net to catch him to give him his shots. She cut his nails, wrapped each paw in bandages -for protection- and put a collar on him. All efforts have proven uselss. He can still maim at will.
I dread the day he comes home. If I have to give him meds, I'll be wearing long sleeves all summer... if I still get to keep my arms.
So for James Herriot's sake, do teach kitties to go peacefully into the vet's office.
