Too hard for little teeth?

Hi there! I've just aquired a male salt-and-pepper named Basil and I went and bought some high quality light cat food for him because he was eating what looked like kitty litter. I've given him a few kibbles as treats, and it seems the kibble is work to chew.

In my pre-hedgehog research, I've leared that many hedgies have teeth problems in my mind perhaps due to hard cat food. Should I moisten the kibble before he eats it as to prevent tooth damage?
