What to do about growling. I needed to move Johnny's bowl. He'd picked the Lily's Kitchen food out of it and put it on the ground, so I picked the food up, put it back in the bowl and moved it away from where it was onto a towel. Johnny growled really quite loudly, I've seen videos of cats fighting and it's the same growl I hear just before they attack. He didn't attack though. I'm not sure if I should back off when he's growling, or if I should challenge him when he growls. I don't want to upset him more, but I do want to make sure he doesn't think he's in charge. This time it didn't amount to anything as I was just moving his bowl, but if it happens again should I be picking him up and moving him away from where he was as a way of challenging his behaviour, or is that going to make it worse?
