Love it or hate it!
We have 4 kittens plus their mother. 2 kittens loved this and so did their mom. When their portion has been eaten, they cry for more!
The other 2 absolutely hate it and I can't get anywhere near them with the tube without them trying to get away and avoid it!
I think it must be good for them, because the 2 kittens who ate it every day grew much bigger and developed more quickly than the 2 who didn't eat it!
So I suggest trying it because you never know how your kitten will react!
