Package Includes:3pcs spiral spring toys with 3 different colors,They are pretty durable, we have cats that like to chew through everything but they haven't yet with theseVariety Toys:kitten toys a good size and very durable. The spring area works well and the sticky suction cup can be easily placed on a wall or door. The fluffy ball on the end is a nice size and my kitty loves it. The nice part is both ends can be removed from the ball or sticky part to add different things to them at a later date if desired.Interactive Cat Toys: They can get lazy cats moving and boost their energy by attracting them.Instead of a suction cup it is a plastic disc with adhesive. There is NO WAY Im going to put an adhesive that isnt removable like 3M on my walls or woodwork in my home. The only suitable place to hang it is on a window, that the adhesive residue can be safely removed with flat blade later.Adjustable-Elastic:With elastic rope, the length can also be adjusted from 29.5-71 inches. The ball will be pulled by the cat and fly around, trying to catch it but unable to catch it, which will drive the cat crazy.The little bell on it is not loud. The ball can even go inside the box and they like to find the surprise insideKeep Your Cat Entertained: our spring toys for cats are nice for your cat to entertain themselves, keeping your cat busy and having lots of fun even without your company
