I found one of Delilah's old catnip toys and decided to see what would happen if I gave it to Sophie. Lolly wasn't terribly active on 'nip. She'd rub her face all over it, then go take a nap. Sophie? She bats it across the room, rolls around on the floor with it, bites it, rabbit kicks it, grabs it with her paws and rubs her face all over it, then goes to take a nap.
Ah, drugging the cat. Wonderful Sunday pastime.
