Is my 4 month old kitten eating enough?

[NekoHK]

I have a 4 month old british shorthair kitten and she weighs 1.6kg. She eats 3x a day and never more than 40g of raw food at a time so probably in the range of 100-120g per day. I've left out kibbles for her as well but she only ever shows interest in these at night. From different websites I've read that she should be 1.9kg by now and eating 160-240g raw food per day. Should I be concerned she's not eating more? She's playful and uses the litterbox regularly so my only concern is that she's on the small side.

Feed her as much as she will eat. Kittens are always growing and expelling energy so they need a lot of food.
