Hi Dcat,
We had Chico done. We called many vets and it just so happened that my fiances vet was the cheapest. We had one leg quoted between 1200-1600 dollars. Unfortunately the injury was congential and traumatic (he fell off a section of the stairs when he got into a scuff with my parents...
My cat was just diagnosed with luxating patella in his back right. The vet recommended surgery as it is a grade 2. He quoted me anywhere from 1700 to 2300. I live in Canada so I am guessing it is more expensive? I am saving for a wedding unfortunately and need all the money I can save right...
