I am updating my article on the usefulness of the SDMA kidney test.
If your vet  has followed SDMA levels in your pet, perhaps you would 
share those values with me. RSH email

These growth curves are general approximations.

Your litter will grow at its own unique rate.

What is important is that you plot a curve for your own cub(s)/Kitten(s)

and be sure that they continue to grow at a smooth, steady, rate.

Male & female cubs are born at similar weights. But male cubs soon

overtake the females.

This graph will improve with time if you send me your data to include.
