How much is too much to spend to save a pet's life?

I just spent $1,500 to save my cat's life. She had a dental abcess and her face was swollen to more than twice it's size. With emergency care and dental extraction the cost was about $1,500.00. I never hesitated to say yes to the vet. Later though I wondered, how much is too much? At what point would I say to put her sleep rather than pay the bill? By the way, we're considering changing her name from Maggie to Scarface because she has a big scar running down her face from the outside corner of her eye to the corner of her mouth. It just seems appropriate...

i've raised several cats from kittenhood to adult. i love all my cats. but only once was i in a position where i shelled out a lot of money for what i thought would save her life. it didnt. i realized that the vet took advantage of me. but then on the other hand, if i had a ton of disposable cash, i would have used it on tiga. what owners need to ask vets is what will the quality of life be for my pet if i have this/these procedures done? tiga had fluid in her lungs. i should have known right then and there to put her to sleep. but i paid to have the fluid removed and she was miserable for 2 days in the vets office. although she looked better the fluid was coming back. so i put her to sleep. it was a horrible feeling but i had no more money. whatever decision is made for the pet - always remember that you gave them the best home and life that you possibly could.
