BerganTwinkle Ball Replacement, Assorted Colors,70135

Great seller, prompt delivery, excellent product. Recommended.

Great, Cat loves it!

Fit perfectly into the track. Quieter than the old ball. Just pull the battery safety tab and the ball is ready to light up. There are now two LED lights in the ball (the old one only had one), so the cat is very focused on it and willing to play for longer periods. Very pleased.

When I got my twinkle ball to replace a ball that was lost with the Bergan Turbo Scratcher it worked for a couple seconds, I thought, WOW, that was a waste of money. But after a few minutes with one of the cats batting it around it started working and has now worked perfectly for almost 2 months.I'm not sure if they would be just as amused with a regular ball as opposed to the twinkle one but this was what was available. My problem is they tear up that cardboard in no time and it's expensive to replace.UPDATE: April/15. The lights just went out. Enjoyable, but I'm not replacing as spending enough on the cardboard refills.UPDATE: May 27/15 Actually the lights came back on about one week after leaving the April/15 update. And it's still working fine. Magic, I guess.

One of my cats, the younger one, loves these and I have 2 and he likes to run back and forth between them keeping the balls in both scratchers rolling. Not as interested in the scratch pad. Yeah, he is a bit OCD and high energy. (My older cat is meh about the toy/scratcher YRMV). Little cat managed to get one ball out after 8 months of very hard whacks sometimes for an hour straight. So I am getting a spare because the original ball is currently MIA under some shelves.When I open the Amazon box, there is a magical twinkling. Oh no, the tab to protect the battery from discharging had been pulled before/in transit. I'm too lazy to return (and my cat is not keen to wait longer for a replacement) but I am crossing my fingers that the battery life is still reasonable after it twinkled through the shipping process.
