but if I did, I would let them know that unless there is some exceptional reason to redo any tests, they would have to use the test results from my vet. In no uncertain terms, I would let them know that I cannot afford to have the tests redone, especially if I will possibly need money for treatment. Sometimes, we have to just take the bull by the horns, come what may. This clinic may just refuse to see your baby if you refuse, but I have the sickening feeling that this is a money grab....like they will not get enough money if you can treat it, and choose to.
I know that it is hard to find another oncologist close to you, so I don't know what else to suggest. I personally have had to deal with cancer in two cats. Both times, I chose to do nothing but have tumors removed when they were bad enough to cause other problems. I don't think that I could have put them through a lot of treatments. But that is me.
Wishing you well with Izzie. I hope that there is a chance for your furbaby.
