Hello, my eleven week old kitten seems to be teething. Her current favorite teeth-soothing toys are cardboard, kicker toys, and a wool ball. I'm curious if there are any other materials that would be beneficial. A local pet supply store sells wood sticks (I can't remember the type of wood!) but I'm concerned for splinters or intestinal blockages. Alternatively, do cats enjoy frozen Kongs the way some dogs do? She's very fond of the "cat gogurts" and while we do squeeze some on a lick mat for her, I don't think she's getting the back teeth chomping she's looking for via licking.
