I really hope part of her tail doesn't have to come off, but if it does, it's probably the most non-invasive thing to be removed.
Ivan had a broken tail, the top third of it had a kink and went off on a tangent. Then a few years back the top inch of his tail just fell off! No warning, I swear. It was a total trip...of course we took him to the vet and they told us it was totally normal. Sophie's pom-pom is adorable. I think she could be the style guru for your neighborhood. All the kitties will have pom pom tails pretty soon! But fingers crossed all is benign.

Did I miss chat? I feel like I haven't been there in ages...but didn't see an email about it tonight.
