Hello, we were given a cat toy by my friend- it's one if those pen lights that shows a red dot and the cats run after it. My Bella went mad for it, running around and rather enjoying it . However , my husband hates them and said he watched a programme that they make cats lose their natural hunting instinct or something. Is that rubbish? Bella seems very un interested in her other toys now and when we finish she miaows and is on edge for about an hour. Any thoughts??
