The real reason kittens nurse only for 6-8 weeks is because of human intervention. Since they are capable of eating solid food, people go ahead and remove them from their mothers to place them in homes. But 6 weeks is still a bit young - even the Humane Society won't place kittens until at least 8 weeks old.
If you donât have a lot of experience with nursing moms and kittens, itâs a good idea to bring momma cat and babies in to see a vet at around 1-2 weeks to make sure everyone is doing well. Itâs very important that kittens are gaining weight steadily, so youâll need to monitor their progress week over week.
