Clicker Training for Clever Cats (Martina Braun)
This is my go-to book for clicker-training; it has lots of photos that aid in the process, and has an entire section on behavior modification.
These are simple clickers, a bit quieter than the classic “box” style clickers (good for not startling cats with the sound). Also comes with wrist straps which are very helpful!
These are awesome cat treats which can also be used during clicker-training; just a lick will do! These are also great for giving medications or an any-time treat. This link is for 3 packages of 4 meat-tubes each (12 altogether).
Karen Pryor’s “Clik Stik” has a telescoping target on it which means there’s less juggling with clicker and treats and a target if you’re using one. Very convenient.
