How to feed young kittens
You’re going to have to take on the role of being mama cat. This requires a few things, so here are some suggestions.
Young kittens must be bottle fed, and the best artificial nipple is Miracle Nipple. Use KMR (kitten milk replacer). Do not give your kitten cow’s milk, chances are it’ll upset their little bellies.
Hold your kitten upright while feeding.
BTW, when kittens really suck, their ears may wiggle!
Kittens have to be burped like babies.
Then, being mama cat, clean your kitten’s face with a soft cloth
At 5 weeks old, your kitten can begin to eat solid food. Some kittens do better to transition to solid food by mixing it with KMR to make a gruel, gradually decreasing the KMR.
