Awww, hating on the rats. I had a pet rat named Nickie, he was a love. Used to run my finger on the carpet and he would chase it with glee, he would squeak and then do little back flips when we were playing. You don't know rats until you own one and get to know their nature, they are very loving. Now alley rats ... well you can compare them to homeless folks, they become feral and in survival mode all the time so of course they look horrid and greasy and will do just about anything to get food, you would too if you were on the streets. Plus folks have to remember, man "kind" keeps taking away natural habitats for woodland creatures like that so they adopt as best they can. They have just as much right to be here as we do but all we do is continually ruin their habitats by over building, polluting and all the other horrible things that man "kind" does.
