So, my cat Loki, who is a nuetered 1&1/2 yr old male, shares the house with his brother Apollo(nuetered male cat)& sister Tinkerbell(non spayed 8MO old female Pomeranian).. he is always comming up to me, meowing talking, and or laying on me like an infant. But when we play, he is ruthless with his claws and teeth, it's crazy cause u don't expect that out of him when u see how sweet he is!.. how do I tell him not so rough?
