Does anyone else's cat do this? When we pet Phoebe and she starts purring, she likes to lick our arms/hands/fingers and will lick about 3-4 times and then do a very light bite (like a love bite) even while we continue to pet her. She keeps purring and will continue to follow this lick 3x, bite, lick 3x, bite pattern. I don't think I've even encountered another cat that likes to do this. Since she's not hurting us, should we try to stop the biting (I'm guessing by not petting her once she tries to bite and then ignore her)?
