gosh thats so odd you saying that about her eyes! my daughter says Gizmo looks like devil cat cos her pupils go huge!!!

How old is Gizmo?

Sky is almost a year and he still nips and bites, a bit of nipping and nibbling is a sign of effection, sometime if im giving Sky a cuddle he'll use his paw to get my fingers to his mouth and he'll nip them, but there is nothing aggressive in it.

Cats will often nip and bite if they are being ignored or they dont have enough toys to stimulate them.

The most important thing to do is make sure you're playing with Gizmo enough, and that each time he does bite you and it hurts or feel aggressive that you make a loud noise, yelp out like an animal would do if it was hurt - it sounds odd but it sure does work!
