i agree with Tabbylove, looks pregnant to me. as sad as it is to have to spay and abort it probably is the best thing, unless you are confident that you can find the kittens homes.
about 2 years ago i had 2 mommies show up at my colony with kittens in tow and i was lucky that i was able to get them all into a no kill shelter. if that same thing happened today it is very doubtful that i could find anywhere for a kitten, much less 7 of them.
