I had the same issue with my kitten - he was full on diving and grabbing at my face! When he was snipped he calmed down straight away.

I also had issues with the cats jumping onto tables and the bathroom bench. You have to be consistent - pick them up and put the on the ground straight away with a firm No. If they keeping jumping up, a little tap on the head and a firm NO can help. If this also doesn't work, put them on the ground, hold them down near the neck (not strangling them or hitting them) and again with the firm NO.

I'm not sure if you have ever seen 2 cats play fighting (or even fighting), but they always aim for the back of the neck. This puts the cat into a 'submissive' position and lets them know who is boss. Another trick, is when saying NO, look them in the eyes and do not back down - again you want to show that you are the dominant person in the house.

To see if the cats are getting the message, look at their poo in the kitty litter - a cat who thinks he is boss won't cover his business.

good luck
