Thank you for all the advice and kind words! I know Pippin will be ok. It's just scary whenever a pet needs surgery, and I think it's worse for cats. One of our dogs Marta has had two knee surgeries and amazingly, still loves going to the vet just because she gets extra attention and gets to have new people petting her! Pippin will hate being there overnight but I know he will be glad to get home and hopefully will recover very quickly. I will update on Tuesday when he is home again.
