I have to agree with Donna. IT'S TORTATUDE. Our Main Coon ET (nick name DIVA) wants to be the boss all the time. She will growl and nip if you do not pet or brush at the right time and god forbid that you stop with out her permission. You will get the growl then the paw, with nails first then the nip.
On the other hand she is just a big lover as long as it is on her terms.
Our little one Boots, only 6 lb, is an in house feral and she has the same attitude. She will come to me 1 or 2 times a month and when she does it is my privilege to pet and/or scratch at her whim.
