I am utterly disgusted! We have roof rats! Last night we saw that Champ had caught one and it was on our back porch. Then as I was going out to get the mail I heard running up the tree and saw a rat jump onto our roof. Luckily my exterminator called yesterday to say that he was coming by for our quarterly spraying. He will also be setting some traps. I just hope they don't get in my house. I am thinking they like the orange trees outside the house and that's how this problem was started.
