No! that is way to young to be selling kittens.

I might understand if for some reason they where abandoned by their mother and maybe some one brought them to the pet store. But even in that case, they should not be selling them. Care for them, the proper way, then when they are older, sell them.

If they are only 4 weeks old, they need special care and who can say, what kind of person is going to buy them, not knowing how to care for such young kittens.

So many pets stores are out for the $$$ over the needs of the pets. It makes me so angry when I see things like these. Pets first, $$$ later is how it should be.
