Suggestions on how you setup the first litter box is my next question.
Also, how did you begin solid foods? He seems to be rejecting any efforts to move to solids. He did take a couple very small pellot sized dry food, (soaked in milk), but I don't think he chewed them, just swallowed them whole.
Solid foods: when my kittens came to me, they were older....but they didn't like eating wet food from a plate. What I did was add water to the food, and swipe my finger in it....then let the kitties eat from my finger. They loved it and still do LOL (but now they do eat from a plate, but definately prefer it on my finger). Anyways, I would bring my finger closer to the plate as they licked the food off, then lower my finger closer to the plate, then finally I stuck my finger in the plate with food still on my finger but food also around my finger on the plate. I'd sneak it out while they had moved from my finger to the food in the plate.
My boys would have nothing to do with dry food that was moist. I know alot of people recommend it, wetting dry food...but my guys would have nothing to do with it. So I just left a bowl of kibble in there with them.
They are 9.5wks now and eating 2 feedings of wet food, plus dry food available at all times. They like both.
ETA: I just checked, and Tiger is 5.5wks or so now? He's the same age that the kittens were when they came to me....I fed them wet pate food mixed with water, 4x a day, off my finger at this age... they would nibble on dry, so I left a bowl in there with the dry, and found they would eat some of it overnight.
