Abby and Bo love catnip. I grow it myself and they like it fresh or dried. Hanna loves the bubble nip (soap bubbles infused with catnip scent) but I don't know if that's from the scent, or if she just likes the bubbles. She doesn't eat them, but will watch forever.

Hanna will come up and sniff the catnip if I put some down for her, but she isn't too interested yet and will usually go over to see what the other cats are doing with their catnip, leaving hers on the floor.
