Help Mr. Pickles' Vet Bill

Mr. Pickles scared his owner by acting like he was having strokes or seizures, but it turns out he has large bladder crystals causing him a lot of pain. The choice was sedating him and catheterizing him to help him be able to urinate and pass the crystals or put him down.  Crystals are large and having problems passing but going slowly. Kidneys are okay. Blood work okay  

Mr. Pickles' owner has stage IV cancer (brain, lungs, liver, colon)  and Pickles is like an emotional support cat. He's with his owner all day and night by his side.

Mr. Pickles' owner is on a severely limited income and self pay for his cancer treatment. The bill is not yet know (as Mr. Pickles will be at the vet for a few days) but it is estimated to be two or three grand.  He had to pay a bunch up front just to get him in to the vet but no other place had openings.

Any help toward the vet bill for Mr. Pickles would be appreciated. He is needed and loved by his owner.
