I found 4 almost dead abandoned kittens 6 days ago their eyes were open ,well some were matted shut but I have no idea how old they are. everthing I find about weight they are about 2 and a half weeks old (they weighed on average about 5 oz each and now weigh 8 plus ounces each )but their teeth are coming in and most are peeing in the box i keep them in .the 2 females get around very good ,the two males are still wobbly. Can anyone help me with how old they are and once I find that out I will have several other questions ? I am going to try to post a short video of them .
