WHO INVENTED THE CATBIBA bird-feeding, cat lover in Springfield, Oregon, USA HOW DOES IT WORKThe CatBib attaches to the cat's collar and hangs loosely over the cat's chest. It gently interferes with the precise timing, and coordination a cat needs for successful bird catching. It works by using the simple principle of coming between the cat and the bird just at the last moment. It defeats all the cat's stealth and cunning at exactly the moment it's needed, and doesn't interfere with any of your cat's other activities. The CatBib ONLY affects your cat's ability to catch birds. A cat wearing a CatBib can run, jump, climb trees, eat, sleep, scratch and groom. If you want to prevent your cat from catching birds, use the CatBib. It's part of being a responsible pet owner to control your pet and to love it dearly. DOES IT REALLY WORKYES an independent University Research Study scientifically proved the CatBib stops 94 of cats from catching all types of birds (not just songbirds)! The lead researcher says: "The CatBib is an excellent product and lives up to it's claims." If your cat is still able to catch birds with the CatBib, e-mail us for tips at CatBib catgoods.com CAN MY CAT STILL RUN AND PLAYYes. The CatBib is attached to the cat's collar by means of a hook and loop closure (Velcro) The material is very flexible, stretchy, soft, and lightweight (less than an ounce), the same material used by scuba divers. Comfortable for the cat to wear. They can run, jump, defend themselves, climb trees, go up and down stairs, sleep, eat, drink and be merry. It only stops cats from catching birds. WHAT KIND OF COLLAR SHOULD I USE WITH A CATBIBThe collar that works the best (so the CatBib doesn't easily fall off and is still safe for the Cat) has a short piece of elastic built in (search on for: "Cat Goods, Cat Collar, Elastic"). Quick release collars can release with the CatBib and will be lost. DIRECTIONS 1. Check to make sure the collar is loose enough for the CatBib to slide easily back and forth. The CatBib should be gravitating to the hang over your cats chest to be in position to interfere with hunting. 2. Make sure the CatBib is not hanging up on anything like bells and tags. 3. The CatBib should be about 1 2" off the ground. You can adjust the CatBib up or down as much as an inch, by moving the hook pad up to the top of the loop pad. You can also trim the bottom as it's soft neoprene. SAFETY WARNING Use only with a elastic stretch collar or breakaway collar. The elastic stretch collar (look up our collar : B07P6MGT52) is recommended as a break-away collar may open prematurely and the CatBib lost.

We recommend starting with the small CatBib, and moving to the large if your cat can outsmart it. EASY TO CLEAN. Made of thin neoprene backed with nylon. To clean, wipe it off with a damp cloth or throw it in the washing machine. Hang to dry. WORKS BY INTERFERING THE CAT's TIMING DURING A BIRD STRIKE. DOES NOT INHIBIT normal day-to-day cat life. They can still run, jump, climb trees, eat, sleep, scratch and groom.
