Don't feel like your over reacting. It's better to see the doc and be sure. I think she is ok and you can laugh about it later. Pervy is the same way. You just can't tell it because of all her hair. I can feel her pouch and it worried me too. Maggie Sue is the same way and they have the same mother. Stubby (who also has the same mom) is the only female of my group that doesn't have it. I think she is just the exception to the rule!!
Keep us posted on Ms. Emily.

You're a good cat meowmie to have her checked!
