Alison, you mean valerian, like the stuff I use as a relaxant, and in stronger form, to curb muscle cramps? The smell of the stuff makes me hold my nose when I take it, so it would stand to reason that an animal would like it! Do you put it in toys or what? Surely they don’t eat it!
We play with all the little balls, sticks & string w/feathers, etc. Once he catches it, he puts his weight on it so I can’t get it back. (Literally, he will put both front paws on the feather or whatever, stare at you like, "this is mine"). Then he likes to chew on the connector between the feather and the string. He’s broken more of them than I can count.—Shirley
