Why?

The mosquitoes are very active this evening. They have gorged on my blood. Equally disturbing, I just realized there are no crickets chirping, and I don't recall hearing any for several nights now. Maybe I just wasn't paying attention and didn't hear them, but maybe something happened to them some time ago and I didn't notice. I have no idea what would befall an entire population of crickets, though. Could the feral cats have eaten them all? If so, why can't they eat the damned mosquitoes? They'd surely be tasty, being full of my blood!
