Sure, I'm playing w/ Loki more than usual + petting + kitty treats, etc. Makes sense about the dominance thing, too. I'll scout around and see what more I can dig up on this. Thanks!
One thing I didn't even think about was that the stray might have diseases, most notibly feline lieukemia or FIV (kinda like cat HIV), that Loki, being an indoor-only cat, would be particularly suceptible to. I have a friend w/ 3 cats. Two of em got FIV -- one died and the other will die if it ever gets sick. Pretty sad situation.
Anyhow, I took the newbie to the vet today for shots, etc., and they're doing blood tests to check on the FIV, etc. --
just in case! I won't hear back about the results until Friday, so Loki will just have to wait to meet her new little friend / mortal enemy.
I'll try to take & post pics as it could be kinda funny...
