These fun little sticks are actually the branches of the Silver vine bush! In the very center of the stick you can see a very slight color change from the pulp of the stick. That is the good stuff cats crave! They'll love batting and chewing on them, and you'll love that the chewing action helps clean tartar and plaque off their teeth. If your kitty gets a lil bored with the sticks, you can strip off a bit of the bark with a knife, to freshen up the silvervine aroma.
This product is NOT recommended for kittens under one year. Kittens can be silly, and might try to swallow pieces of bark too big to swallow, choking them. Cats older than a year will have fully developed instincts, including the instinct to spit out bark pieces too big to swallow.
