Oh, Cutezz, what a nasty thing for your cat to endure. I'm so glad the problem is fixed now. Here's wishing your kitty many more good years. Yes, cats do get very set in their ways as they age. (sort of like people) Mine eats only one particular kind of cat food. I have wasted a fair amount of money trying to change his diet, but he just tries to cover it with the carpet.
Poor P.C. You must have been so exhausted waiting for your cat. That's why I keep my patio door deadbolt-locked about 3 inches open. He can come and go as he pleases, without keeping me awake worrying half the night.
