Highly Entertaining Toy That Keeps Dogs Thrilled, But Smart Pups Can Disassemble It
This interactive ball is an absolute hit with my dogs, and watching them play with it has been incredibly entertaining. Right out of the box, the internal mechanism charged up very fast, so we were able to start a play session almost immediately. It blinks blue when charging and solid green when charged. The unpredictable moving and bouncing motions caught my dogs' attention right away, and they love chasing it around the room. My only critique is that it didn't take them very long to figure out how to pop the inner motorized ball completely out of the outer cage. Luckily, the materials are genuinely durable; even though they separated the pieces, they haven't destroyed or damaged either part yet. It's great fun to watch, but you'll definitely want to keep an eye on smart pups who figure out how to open it up.

Really cool cat toy for even the most picky cat!
Color: A1-Red, Color: A1-Red
I love it, wow. Our cat is picky with toys, but even he was intrigued by it. It really kept his attention, which is hard to do. It comes with three modes: fast, slow, and interactive. The only thing is that hair can get all trapped up in it because it's a wheel, so keep your house clean I guess lol. The tail also came off once, so you gotta snuggly get it on up there. Really cool cat toy though, I'm happy I got it lol

Not worth the money
Color: A1-Red
My small Chihuahua loved this toy. It kept him entertained until it would stop working. He only gets about 10 minutes of play and it's no longer charged to use. I even bought a second one thinking the first one might have been just bad luck, but nope, the same problem. It seems most of these interactive toys are only given 2 to 3 stars. I'm disappointed but more importantly, my pup is even more.

Terrific product
Color: A1-Red
I adopted a 2 year old cat - she’s not much for a lot of the toys I have purchased for her, until this one! At first she seemed very cautious with it - but still followed it around - once I slowed it down (a few different options) she loves to play with it! Great purchase very pleased with it

Fun & Fast moving toy for my cats!
Color: A1-Red
This is such a fun little toy to keep my cats entertained. They were definitely weary about it for the first few days, but started to get used to it and play with it after a bit. I wish there was an even slower option because the slow option is still pretty fast, but at least it gets them up and moving. They will even play with the tail part when it's not turned on. Like others have said, it does collect hair pretty easily, but it's very easy to clean off. I don't have any dogs, but I could see smaller dogs loving this as well!
