My kitty chases everything moving [except the flies in the house.. she finally realized it is not worth it since they greatly outnumber her]
There is poison in the basement which wards off mouse pretty well. We found one outside by our porch the other day. He was hardly moving and so fricken cute that I fed him bird seeds. I felt bad for him..
What if my cat tried to eat a mouse that had previously eaten poison?

I always get so nervous when she eats spiders and ants and etc... those things don't cause reactions in cats though, do they? [they are not venomous spiders, we don't have those in the mountains.]
