kitten development

If you know the date of birth, you can enter it into this calculator and it will let you know if your kittens' development is on schedule. You can also work backwards with it to figure out how old a kitten is if you have no idea when the kitten was born.

Cool!! Thanks!

How do I use this? Rascal was given to me in October 26. The lady said he was six weeks old. So I assumed that his birthday is in the middle of september. My guess is the 21.

Thank You.
