This is a cute toy for my active cat 'Tasha'. She was a little bit scared of the fish first. I decided to turn off the toy and let her smell the catnip for few hours. When she is familiar the fish, I turned it on and let her play with it. Now she plays with the fish constantly and I had to hide it from her, otherwise she would grab it all night long.
The fish toy material is similar to a padded small cloth purse. Its durable and would last from cat's bites. I like the option to recharge the battery via USB. Save money on batteries. The small bag of catnip inside the fish helps a lot, because the toy may scare them at first. The fish's tail wiggles at a different speed each time it was touched. It added some excitement to see the changes of the flops.
If you would like to get a unique toy for your shy cat, get this. They will be entertained all day.
