Husband and I started weaning our 4 week old kitten about a day and a half ago. He is not interested AT ALL. I put his formula in a shallow dish and dabbed some on his lip. He doesn't even try to explore his dish or formula. Today we tried the KMR 2nd step. He sniffed around at it for a few seconds, but again, won't even stay in front of a dish to try and explore his food. He just cries and cries for his bottle...which he recognizes and runs to every time he sees it. I don't want to starve kitty, but he needs to learn to lap food! How long does this take? Advice please we're worried!
