Does What It's Meant To Do!
Life changer for my "Edge-Peeing Pup!" Easy to clean, portable (just rolls up for travel) and does it's job. Very happy with this purchase!

Help training kitten poop
I have young kitten. It is attractive to me to use the Potty Training Tray. Kitten does not know to go to litter box initially. And they even eat cat litter. For safety, the trining tray is a good start to train their poop habit and also help a smooth transition to litter box when they get older.

Great, durable toy
Color: Blue-Red, Size: Extra Large Size 5 (9")
I’ve had this toy for a while now and my dog absolutely loves it. I frequently bring it to the dog park with us and it’s also loved by other dogs. The ball is pretty durable. My dog is not a big chewer but other dogs that play and chew on it haven’t been able to pierce it yet. The handles are sturdy and also still intact. Overall a little pricey but in my opinion worth it.
