Sorry your cat was bitten. It sounds more like a tick to me than a snake. Paralysis and loss of voice is some of the first symptoms you will see in a cat affected by a tick. I have not heard of too many cats being bitten by snakes and surviving. If it was a snake he sure is one lucky little fella. I understand why people don't like snakes for sure especially if they have had an animal bitten or lost to a snake but i try to remember that is this their home too and they were here before we were. If a snake was about to attack one of my pets would i kill it... Sure I would..
I'd have to agree, sounds more like paralysis tick to me. Be mindful that your kitty might relapse. I bottle of injectable vitamin C will cost you around $18 and a needle and syringe a couple of dollars . We keep vit C in the fridge at all times and even administer after the animal is in a coma . I've seen a goat go down after snake bite and be back up and around 5 hrs later. It's $5000 for 2 doses of the antivenin for a dog and my chances of getting a vet here in time are zero. If you are in snake country you should research it .
