Help Pickles out

On 10/15/17 I saw a post on facebook for a cat with an injured tail, so me trying to save all the animals took the cat in. I didnt realize how bad the tail was until I finally managed to soak the bandage off. The vet is thinking anywhere from 700 to 9
00 to treat this, he will be going in later today to get a better idea of what happened and how to treat and fix it, my worry is surgery. I already have 2 dogs and 3 cats but I cant just let this poor girl fend for herself. Any donation of any amount will help her out. Thanks in advance

Update!
Pickles just got back from the vet. The original 700 to 900 is now bumped up to 1700 for surgery due to his teeth being bad and needing to come out.
