My gut tells me it's too early to be worried, but sites online tell me otherwise so I thought I'd best check with you lot. I have fostered litters before, usually slightly bigger than this one (there are only 2 kittens) but not had this issue. Usually kittens are keen to try food at the 4 week range, often a little younger (!) if they're from a big litter. Molly has two kittens, who are fairly whopping in size according to their weights (male 600g, female 500g, both weighed at 4 weeks this last Tuesday). They are going to be 5 weeks old on Tuesday and are not showing any interest at all in solid food. In fact quite the opposite, they don't want anything to do with it. Now their weights and young age tell me it's nothing to worry about yet, the male in particular is huuuge and pretty fat with it (he has a fat pad between his back legs that is actually visible when he walks lol), the female is leaner and more girly in shape, but she is more active too, the male is pretty lazy and laid back. There are a few sites online that say kittens should be eating predominantly solid food by 5 weeks old, obviously staying on mum's milk too til 10-12 weeks. Is this right and there is something going wrong here, or is my gut instinct right in that if they're fat and happy it doesn't really matter? Thanks!
