I would also be concerned that she was removed from her mother so very young. Kittens should be with their mother and litter mates until at least 8 weeks old. Maybe you could find some way to socialize her so she won't become maladjusted.

I second getting a different litter than the clumping. I can't tell you how many times I have heard about young kitten dying because they swallowed the litter (which is common to do when they are very young).
