Once the kitten is three weeks old you can try putting a little mushy kitten food in your finger and holding it up to the kittens mouth. Some will try it this early and it definitely helps get the calories in them.
I feed him every 2 hours even through out the night! Sometimes he suckles amazingly sometimes he refuses and I use a syringe to get it in to him. He weighs 120g now. The milk I’m using is this one. I am going to try goats milk. And he is going to the vets on the 27th.How much and how often are you feeding? Are you feeding throughout the night? He must gain weight.
Which formula exactly are you feeding?
Little update!This lactol should be ok but try with goats milk too if you can.
