Congratulations on the new furry addition to your household! She looks like a real sweety.
Too funny on your name choice I also had a little shelter girl I named Ripley, also after the character in Alien. She had a little hernia on her belly and every once in a while (until we had it surgically corrected when she got spayed) it would pop out and she got a little bulge on her belly under the skin. I could pop it back in with my finger. All we could think of was the alien popping out of the guys chest in the movie so she got named Ripley.
