our 10 week old kitten has taken to playing really roughly with us all, claws out and very scratchy but obviously still playing. I think it's because she often plays with our older cat and of course they play rough. Don't really know how to discourage her, we are spending time trying to amuse her but at times I have to shut her out the room as she is hurting my dd's and myself with her super sharp claws. Any ideas?
You could try yelping like a scratched cat when she does it... that sometimes gives them the message that it hurts you just like it would hurt another cat. They don't really understand human noises as well!
Otherwise, play with her with a good thick oven-glove on, so you have some protection from the claws.
I lived in a house with two kittens/cats for a while. The first method worked on one of them, but the other just didn't seem to get the message, so we used the oven glove on him!
