I received these products for free from the Spotted by Petco sampling program in exchange for my honest review. I have multiple guinea pigs who are quite different in personality so I figured at least one was bound to love these balls. Well, I was right: Exactly one of my wheekers like these balls. All of my pigs approached the balls to sniff or try to chew on them, but then within a matter of seconds their interest faded. My boy, Bacon, however loves the larger balls in the set. He chews on them, pushes them around, and picks them up with his mouth just to playfully toss them. He doesn't seem to care about the smaller balls. I think the general concept and construction of these balls are great, but they could be better. I think if they were made from a scented wood that my pigs would be attracted to (like apple or pear) then they would be better. I probably wouldnt purchase these simply because the majority of my furbabies don't like them, but I will admit the retail price of five balls for approximately ten dollar in stores is quite reasonable nowadays.

These balls are a nice size and quality. I thought my bunny, who chews on everything, would like to chew on these. He does throw them around his cage to play, but I was hoping to give him some appropriate chew toys.

Lily the rabbit loves these! She gets so much joy out of using her nose to push the balls around. She eventually enjoys chewing them. I love these as an enrichment for her environment. Well worth the purchase for any small animal!

I really appreciated the size differences. My bunny and guinea pig like to chase the smaller balls, but chew the bigger ones, so it was nice to get both sizes in one package. All of the balls are pretty sturdy and have stayed together, despite being chewed in parts and a couple of the pieces coming off. Multicolors are also aesthetically pleasing, while still appearing natural.
