I don't mind bats, and I know that they are very helpful to have around to control the mosquito population, for one thing. But I've also read that if you see a bat under unusual conditions, it's got a considerably higher than normal chance of having rabies. The Centers for Disease Control web page about rabies notes, after commenting on all the reasons to be tolerant of bats:
However, any bat that is active by day, is found in a place where bats are not usually seen (for example, in a room in your home or on the lawn), or is unable to fly, is far more likely than others to be rabid. Such bats are often the most easily approached. Therefore, it is best never to handle any bat.
I don't care for bats when they are flying at me. In my first few months of living in Northfield, I once found myself shut into a basement laundry room with several bats circling me. I shut the door after the first bat I saw flew out into the larger basement. I thought I was now safe, only to find at least a couple more still inside with me. Eeek. After I got myself out of there, I called my mother in California to tell her, and she said, "But Pen, bats are so interesting! (See where I get it?)
Another time I was alone at work at my desk in an old building on a college campus. After I'd been there quite a while, an odd bit of color caught my eye, and it turned out that a small bat was quietly hanging on the short filing cabinet next to my desk. As in, about two feet away from my right arm. The poor thing was dead under an office chair the next day, and I carefully and discreetly buried it in a flower bed outside.
While looking just now for the photos I'd taken of the bat the first day we saw it, I came across this photo of our two cats, Callie and Jeeves, earlier this summer. They are undoubtedly watching either a bird or a squirrel, as they are looking so attentively through the screen toward the area right under our bird feeders. I like the similarity of their posture as they watch whatever it is. Hey, cats rhymes with bats. Good enough for me.
