Guys, I need advice.

I have around 8 month old cat. the problem is, he only eat wetfood now, currently introduce him RC Indoor 27 & RC protein exigent, but after a day, he puke out the kibble. now dont want the kibble at all. only want wetfood.

Any ideas how to deal with this prob. or should i try to use another brand of kibble, like brit prem?

Any suggestion? TQ.
