Cidney, I am truly sorry that the surgery didn't work for your baby
In most cases, it is a successful surgery...I truly thank God that everything went well with Miko. We were really scared just like you and your husband, but then our vet told us that it was actually somewhat of a common practice with cats that develop stones/crystals. And I am like you, if I suspect something is wrong, I don't just take a vet's word for it anymore...I learned that when Miko was a pup. They told us that he wouldn't make it through the night and that maybe it would be best to put him down!! They were crazy...
You are giving wonderful advice!!
