I'm you found something he likes my two love Applaws also they like the kitten dry as well which is also very high meat content.
If you are worried about him not getting enough nutrients you can also give him nutrical as a supplement it also helps them grow to their full potential. Using it made my teeny girl grow from 0.4kg at 13 weeks to 2kg at 21 weeks.
I recommend the kitten one as it also has extra Taurine but sadly its something you need to import it but it's not too badly priced atm
