Hi, my cat Tiger is very sweet but has a slight problem. during the summer my cat goes on her killing sprees and not only kills chipmonks, mice, birds, and bugs, but she actually took a crack at a squirrel which bit her ear. :x she started caching animals like birds or chipmonks and not killing them but releasing them alive in the house to chase and torture them in the comfort of her home. we can't have her bringing in animals and she would die if she couldn't go outside, summer is coming...what do i do?
