When I let my cats outside on a sunny spring day, the first thing they do is eat grass. They're like miniature lawnmowers. Later, they hack the grass back up (like a hairball). Why do they do this? (Meaning: why do they eat the grass in the first place, and why do they then spit it back up?)
Our three cats have fleas and worms. We've tried a couple of over-the-counter products, but they haven't helped (especially with the worms, which are our biggest concern). The vet wants to sell us expensive remedies, of which we are very skeptical. Before we shell out big bucks for the stuff the vet suggests, are there other things we should try? What has worked for you?
