I recently came across 6 abandend kitten. I am guessing they are around 4 weeks old. I have been bottle feeding them for a week now. How do I get them to drink out of bowl. I am finding I don't have the time to constantly keep bottle feeding them. I have tried all I know to do from mixing in soft food with the formula to just straight formula. If anyone has any advice on this matter it would be GREATLY apprciated. Thanks
