How can I teach my 12 week old kitten not to bite my hands? I've read about many different techniques . I've read to sternly say "no." I've read to say "ouch" loudly. I've read to use a squirt bottle. What's the best way? Any suggestions?
Try not to play with her using your hands. Use a teaser or her toys to play with her. If she goes for your hands while you are not looking, distract her with a toy and place the toy near her mouth when she's biting you and move away from her. Always have toys lying around so that whenever she bites, her toys are within reach.
Kittens go through different phases in their kitten life. So expect surprises. Do not use a a squirt bottle on her please. Here is an article explaining why :- 5 Reasons To Never Spray Water On Your Cat
