My granddaughters cat has a tumor in its nose will ivermectin work on that ?

Somewhere I read something about ivermectin for pets? I will check my notes. Might take a while. I can tell you that I do give my dog the “old” Heart guard which contains Ivermectin, and he tolerates it very well. (The newer heart meds made him very ill). But so you know, I am not a vet or a physician! 🥰
