Hey everyone i have a 6 month old kitten, Tigger. I just brought home a baby kitten, Angel. Now the problem is Tigger keeps goin after her and biting at her and grabbing a hold on her. She lets out a meow and will run away, but than pretty much comes back for more? Should I be worried about this or will they eventually get passed this? I'm worried that he is gonna actually hurt her or something. What should I do to help ease the process? Thanks for your help everyone !!!!!!!
