Catnip isn't the only thing that makes cats Physco. My gray tabby loves the smell of bleach. I would put bleach in my sink and would find her afterward with her head down the drain sniffing the bleach aroma. Then she'd get kind of whacko. She also likes the inside of a carrot bag. The smell of carrots on plastic makes her mello. I mean really mello. Course my dog likes cauliflower and cabbage. I must be raising alien animals. They are a hoot!!
