Yesterday when I went out to feed the ferals I saw 2 little kittens by the food dish. They ran off and hid so I never got a good look at them. I'm trying to get an idea of how old they might me. I'm thinking they could be 7-8 weeks?
Solid means dry food?
Kittens can eat wet food at 6-7 weeks
If you want to feed them dry food you can smash the kibble and mix it with some warm water because their teeth are not used to chew
