What's the cost of to put my cat to sleep end all of thinks like that

Prices can change and it may depend on the weight of the pet.

Call them and ask. No one has their price list.

Thankfully I haven't had to deal with that in a while. I would call for pricing. You have my deepest sympathy. I know how difficult this is. They are very sympathetic and will let you stay with your pet during. Very important to me.

You would have to call them, I've had a sick cat treated but haven't had to put 1 to sleep
