The Wheeky Treat Ball for guinea pigs, rabbits and small pets is an adjustable-opening treat ball that is a great boredom buster for guinea pigs, rabbits, rats, hedgehogs, and all small pets. The Wheeky Treat Ball is not a chew toy, but an interactive treat ball that provides a fun mental and physical workout for your pet. Put your pet’s favorite kibble or small treat (pea flakes, diced carrot, or dried fruit or herbs) inside the hollow ball, adjust the size of the opening, then sit back and watch the fun! As your pet rolls and pushes the treat ball, food falls out, thus encouraging more play. Please supervise your pet when they are playing with this and any other toy. 1. Choose a small treat that your pet really enjoys, such as kibble, green pea flakes, dried herbs, or small diced carrot, and put some into the treat ball. Make sure the size of the treat is small enough to fall easily from the opening. 2. Start by shaking the ball and giving your pet a treat. Do this a few times, so that it gets their attention. Soon, your pet will start to associate the shaking noise with treats. 3. Make sure the closure on the ball is wide open to start. Place the ball on the floor with the closure underneath, so that treats will fall out easily. 4. Put the ball on the ground in front of your pet. Take a small piece of diced vegetable or other treat, and place it on top of the ball. After your pet eats the treat, then put another treat in front of and behind the ball. Do this a few times until they seem to understand that touching the ball means that treats will appear. 5. Encourage your pet to nudge the ball. You may need to keep hiding treats on top or behind the ball until he/she understands that moving the ball will make treats appear. You may also want to try different treats to see which one they like best. The Wheeky Treat Ball is a great way for you to have fun with your pet! 100% quality inspected in USA.
