Okay, I have four very energetic, spoiled, naughty cats. Lately, my 2 younger cats: GARY: 2 yrs and TINSEL: 1 yr 2 months, keep bringing in animals (birds, mice, lizards, grasshoppers, frogs, & small grass snakes). When I come home or wake up in the morning, I go into my bathroom and about once a week there is a new dead creature in my bathtub. They won't just "play" with these and animals outside they run around in and out with their "prizes" but even if I put them outside, they wait until I open the door and run in with the dead animal. My question is why my bath tub????? They never bring them into any other rooms, but they know that they aren't even allowed in the bathroom. Other people leave the door open and I find them in there. Why do they do this?
