Interesting! Our little cat has had a biting problem of late. She's long been fond of biting me on the leg or instep to get my attention when I'm working. I scold her and toss her out of the office, but the problem is, I'm so intently focused, I don't notice the less intense attempts to get my attention. She's figured out how to run her teeth across my leg, though, which startles me enough to notice, without causing an actual bite. BUT (I know, I rambled on...) lately she's taken to spontaneously biting my husband. Eyes wide, ears back, she'll just fling herself at his arm. I know he recently discovered a packet of cat treats that had been hidden away in the back of the fridge. Maybe she'll stop if he stops giving them to her?
