Advice

If this isn’t allowed just let me know but we got a kitten from a family member who doesn’t want it and she says it was ready and was eating food but according to mine and my husbands calculations it’s maybe only 3-4 weeks old! It is walking around following my daughter meowing it won’t touch the food or water we give it ive never had a kitten so I don’t really know... what do you think advice tips on anything would be great thanks
