Free: Contests & Raffles.
Animals dont think like humans. Cats get bored easily so changing the sounds gets and keeps them interested. I really dont think a cat or coyote is thinking "hey there is a rabbit over there...wait now its a mouse whats the big idea?" They just hear an animal in distress and think "food better get it before someone else". I dont think their "logic" meter is very high. I have actually seen a coyote sitting watching as the woodpecker sounds was going and as soon as it turned to the high pitched rabbit it came running in. As soon as it saw my Mojo Critter it took off like a rocket.
