We got 2 kittens in mid September. We also have an old cat, he's 19 years old, so we hadn't had a kitten in our home in quite a while. I decided some teethers were needed and I took a chance on these. They absolutely love them! They hold up well to hard play and lots of chewing. Our 2 little boys came from the same litter and "spar" constantly. They also enjoy tugging at the same toy, and these little things have held up extremely well! The little wooden ball that dangles on the side is very easy for them to break open. That's not a deal breaker for me, neither here nor there. That wooden ball is not the main part of the toy so it's not big deal for me. They have put every single one through kitten wars. Every one of them is still in good shape and safe for them to play with. They both love them too. These serve their purpose well, as they both will seek this out to chew and play with over chewing or biting on random things in the house.The price was excellent. Its currently December 29, 2024 and I purchased these back in September of 2024. Not one of them has had to be thrown away. This is definitely a good option for any kitten. They don't make any noise. Also - since our boys broke the wooden things on them all almost immediately, if there's a stray one on the floor, it doesnt hurt to step on it. As a mom who occasionally steps on Legos, I greatly appreciate that. I also appreciate how quiet they are. No bells, no squeaks, no nothing. The colors are nice and vibrant, and they don't seem to bleed color onto anything else when wet or damp. The green one somehow landed in their water bowl, they got ahold of it whike still wet, and drug it up on my cream color couch, and it was there for who knows how long. There was no color bleed onto my couch fabric so thats a great thing too! The size is perfect for kittens, but its also fine for older, larger cats too. Our old boy sometimes will play with them happily. Though, I do think the kittens find them more fun than old boy does. This product is definitely a great buy. I have happy kittens who are no longer chewing on items I don't want them to around the house. Its a great option if you need something for teething kittens!
