What a beautiful tabby. Im glad your keeping him. I had one who looked identical to Finn the only difference being his eyes were rounder and sea green. His name was Henry and he came home one day vomiting blood. Vet said he ate poison and since its been in his system for so long even if they tried to save him he'd likely not make it. I spent over 200 hundred dollars that day just to have my baby put down.
Oh no, I am so sorry that your baby got into some poison. That is the most helpless feeling to know they are suffering and you cannot do a thing to help them get better. Orange tabbies are very special cats and once you have one you always have a special place in your heart for them. When we first got our Orange Tabby, Roux, our Vet told us that in her 20 years of being a vet she had never treated one or owned that wasn't sweet.
