Both kittens are male, alert and seemingly healthy looking. Six weeks old. One is 500g and the other is nearly 700g. Is a smaller kitten any indication of future health? The smaller one seems friendlier but we feel the chonkier one may be more robust.
Or is 6 weeks just too soon to know? It was a large litter of 8 so probably all are smaller sharing mum.
Thoughts!? Any experienced kitten breeders that can advise?
