Help with new kitten

Hi hoping for a bit of help I have recently bought a kitten was told she was 6 weeks and ready to leave home we have just discovered she's actually 4 weeks and fresh of mothers milk and never fed from a bowl the vets said to give we a bottle morning and night and encourage her to eat but were really struggling and it's more confusing as she's trying to eat the cat litter any advise would be really helpful

Where did you buy a four week old kitten from? That is way, way too young to leave mom. So is 6 weeks, just so you know.

Is the kitten taking bottles at all? If not, you need to start feeding with a syringe or a dropper, one drop into the cheek at a time. Kittens must be warm and fed only warm milk. She needs a bottle every three hours at this point.

Did the vet tell you how much she weighs? What exactly are you feeding her? She may need to be fed completely from a bottle for another week or two.

Does she pee and poop on her own?

It sounds like she hasn't been weaned yet - kittens usually start eating solid food rather than milk at about 4 weeks. What you can start doing is putting some wet food in the bottle with the milk so she gets used to the taste of the wet food. If she's chewing at the bottle, then she's really wanting to be eating food rather than having the milk. You can try putting some wet food in a bowl mixed with some milk too. Teaching her to eat is a messy process - she will get it all over herself! You can try putting some food on your finger, letting her lick that off, then leading her back to the bowl. She should also be eating a lot more than twice a day at that age - probably about every 4 hours during the day.

Also, the milk I'm talking about is kitten milk replacement - the rescue place I volunteer for used KMR Powder (). And the wet food is Royal Canin Babycat.
