Kittens can start eating wet food as early as 3 to 4 weeks old. At this stage, the wet food should be mushy and mixed with kitten formula or water to create a gruel-like consistency to help them transition from nursing to solid food. By 6 to 8 weeks old, kittens are usually fully weaned and able to eat solid wet food without mixing it with formula. It is important to introduce wet food gradually and ensure it is formulated specifically for kittens to meet their nutritional needs during growth and development.
