I had a cat that looked like that one. Called her 'Mimi'. Kinda eerie to see a pic that looks like her online. (She was an odd mix. Her father was big enough to be more than half bobcat......) Mimi looked more like a Norwiegian Forest Cat, though. Had the ruff on her chest and the ear tips and cheek tufts. And that tail... mind of it's own. Weighed in at 22 pounds, all muscle. Was a very affectionate cat. I raised her from a little ball of fluff and attitude that could barely peek over the cup of my hand.
Geez, I'm a long winded SOB tonight. Must be the memories of that cat o' mine. (Some will dispute this, but I dare them to try and prove me wrong. If you mix a Bobcat and a domestic cat, the resulting half-breed will still be fertile. Just don't get it mad. Where I used to live in Vernon, N.J. the bobcats and housecats were crossbreeding. Got alot of funny results there.....)
Don't tell me, but did your kitty go up in smoke one night, in a puff of lightning? ;-)
