If the kitten ate it willingly, nothing bad should happen. A 4 week old kitten is just at the very earliest stages of weaning, so don't start feeding it solid food only at this point, he/she still needs to nurse regularly.
there are spacial kitten foods.
Twice a day.
No!
Do not be too sensitive, feed him three times a day and after a week you will get the average meal
You can syringe feed the kitten. For more information visit thecatsite.com/t/276288/3-week-old-kitten-not-gaining-weight
Yes it is,its best not to give your kitten hard food when its to young,it can choke.but as long as the food is moist,it should be fine.
All cow's milk is not good for animals including buttermilk. Will cause diarrhea and is of no health benefit. You need to find a formula such as esbilac to replace the Mother's milk. Get a bottle too, can find them in the pet stores and feed the kitten about every 3 hours. In about another week, you can start to add softened kitten dry food, but soak it first until soft. Pour some of the esbilac on top of the kitten food. Offer that to your kitten and she or he will start to chow down on that. You can switch to dry kitten food completely at about 5 weeks of age.
NO! Cats are lactose intolerant and "real" milk will cause LOTS of dogestive issues, especially in young kittens. You need to be bottle feeding the kitten KMR (kitten milk replacement).
When the mother rejects a kitten is often because there is something wrong with the kitten. It's natures way. However, if you take the kitten to the vet it's very possible you could pull this kitten through whatever is wrong, but you will have to be available often during the day and night to feed the kitten and to be sure it has it's medications.
2 a week
I have a 5 week old kitten that my fiancée and I rescued and he's healthy at 1.3lbs
