Can I get my money back from my vet?

I took my cat in because he had urinary "crystals" and was having trouble urinating. My vet said he was blocked and needed to be sedated, cathetered, and have his bladder flushed. They kept him overnight and charged me $547 for this treatment. I picked him up approximately 23 hours later, the vet told me his was better and showed an xray in which he stated there were no crystals present in his bladder and they sent me home with a bag of food and some antibiotics. About 5 hours later my cat was once again struggling to pee and seemed distressed. I called urgent care and they advised me to bring him in immediately. $2000 later they tell me my cat is completely blocked and was headed toward a bladder eruption due to crystals. They said my vet should have cathetered for at least 48 hours and told me they were keeping him for 3 days due to the severity of the blockage. He had a lot of blood present in his urine that didn't flush out until the next evening. Basically my cat came back to me from my original vet worse than how I had brought him in and almost died. Do I have the right to request my money back due to the fact that my vet cut corners by only catheterizing for a few hours and sending him home without checking to see if the catheter actually worked? My poor kitty suffered because of his negligence and in turn cost me about 2600 bucks. What can I do? Sorry if I wrote this in a confusing way.
