Best cat treats for kittens and older cats?

I have just looked into the idea of cat treats I have a 5 year old tabby and I have tried pounce cat treats with her she liked them when I put them in her food bowl but If i used it as a treat she hated it. So I am also getting a new kitten in a few days and was wondering which cat treats where the best for kittens and which were the best for cats
