I don't mind rats, not that I want them in my house, but they don't horrify me...The roaches on the other hand would have me living in my car as soon as I saw one. Seriously.
I had a mouse in my house over the summer, I was on a leave of absence from work due to cancer, and I'd be laying on the couch watching TV and suddenly this little white mouse would scurry across the living room, stop and look at me, then just keep on going. He's no longer with us

I rented a duplex when I first graduated from college, it was a very old brick house that Penn State University owned back in the early 1900's, there are like 20 of them still owned and/or rented out. Some are nice, some not. Mine was a rental owned by the nicest people and good landlords, but it was weird because it was half the house they owned, the other half someone else owned. And there were many, many squirrels that lived in the attic. I'd lay awake every night listening to them play soccer up there. They'd run across the attic, then run back across, and so on all night. And my landlords couldn't do anything because my neighbor, who owned the other half of the house, had to agree to pay half. She wouldn't. I just dealt with it until one night I got home from work really late and just wanted to take a shower and go to bed. There was a metal duct that came from the ceiling in the bathroom, went down the wall and ended right above the shower stall. I figured it was old ductwork from a fan or something that was just never removed. Well that night I got in the shower and was so exhausted I could hardly stand up. Suddenly I hear what sounded exactly like the game PLINKO from The Price Is Right, when the contestant would let go of the PLINKO chip and let it bounce down the board? Yeah, that sound. And out of the vent plops a huge acorn right into my bathtub..."OK, that's it, you're kidding me right?" I just couldn't believe I was having to deal with this...Until....I heard this god awful scratching sound, like nails on a chalkboard, then a scurrying sound, like toenails on metal.....A squeal...And THUMP!!!! SQUIRREL IN MY BATHTUB!!!
Apparently the squirrels finally chewed away enough insulation in the attic to expose the old bathroom fan duct, and they decided that they would throw their acorns inside it for safe keeping. Then one little guy decided to jump inside the duct himself when he couldn't see the acorn he threw in there...I wasn't thrilled about a squirrel seeing me naked and then being chased outside to tell his little squirrel friends about what he saw. I became very popular within their community from that point on. They still write.
I moved out as soon as my lease ended 2 months later...
