This is such a cool toy for a dog or a cat. I bought it for my 28 pound Aussie doodle. She’s slightly laid up after an injury recently so I’m trying to come up with things she can play with in the house without excessive running. This totally keeps her engaged and she loves it. But I have to watch her because every once in a while she’ll just catch it and try and chew on the ball! But I’ve been sharing it with my neighbor who has a cat. She’s borrowing it today and her cat loves it too! It seems pretty durable overall but it certainly doesn’t want my dogs’s jaws trying to crack it into. You do hear a humming noise while it’s running but I think that’s to be expected. Mostly I just love how much it entertains both dogs and cats!!

So cute and entertaining to watch!

Color: pink

Bought for my miniature schnauzer. She didn’t know what to think at first but loves it now. It’s so much fun watching her play and keeps her busy! My dog isn’t much of a chewer and loves the movement/chase of this toy. Wouldn’t recommend for big dogs or chewers as there’s a plastic piece that can come off.

I stops working & doesn't recharge

Color: blue

I just recieved this yesterday 5-23-2026. My new puppy loves it. But after it stopped working and I went to recharge it. it just will not recharge. I currently have it still trying to recharge. so I am not sure what to do other than trying to charge it. I may need to look for something else.

Nice Idea But Won't Last With A Frenchie

Color: orange & blue, Color: orange & blue

My dogs loved the balls, however, withing 30 minutes, they were in pieces. Be careful because these parts can become choking hazards. Maybe they should try to make them a bit more sturdy, then I would buy again. Wish I could give them more stars because I liked them and the dogs did too.
