We've just got two kittens and our children, 6 and 3 keep manhandling them and on two occasions have trapped them in enclosed spaces deliberately. I'm not sure of the best way to deal with this as we've told them a million times to be gentle, and used naughty step when we've caught them being rough.
Eg - throwing the kitten, holding/lifting by paws, putting in laundry basket and closing lid.
Final straw was tonight when one kitten went missing and i heard it mewing and found it in a box in the kids room with the lid on, in quite an enclosed space and it had been there at least an hour.
Don't know how to get them to stop- wwyd?
