answer:I’d say this is just a very unfortunate coincidence. Especially since it’s two different types of cancers and because they both had risk factors (not being fixed before first heat, being white) for the type of cancer they have. Sorry about your babies. :( I’m a hypochondriac and I find that I’m now focusing more on my pets’ health than my own imaginary problems. We have their annual exams/vaccinations this Saturday, and there are a couple of things I’ve noticed that are worrying me. Hopefully it’s nothing and they’re healthy. They’re pretty young (our cat is 3 and our dog is not quite a year-and-a-half), so I suppose there’s a good chance they are.
