Hi, all! I'm in a bit of a quandary. I've been struggling to find ways to tire out my kitten, Rollo (neutered 7-month-old), after my sister moved away with his puppy buddy. The two used to wrestle and take turns chasing each other around the house, sometimes for hours on end. I did try running after him, but he just stares at me! The problem is that Rollo doesn't seem to be interested in any of his toys -- and he has many! I regularly rotate them as suggested on a few sites, and have a good variety (balls, springs, teasers, fishing rods, squeaky toys). He'll play for a few minutes at most before getting bored. I've tried finding other ways to tire him out, such as clicker training (I do two 10-minute sessions a day) and taking him outside on a harness (for about twenty minutes, weather permitting). He has a cat tower and perches at almost every window. But he's still hyper and has trouble winding down for the night. He runs up to me regularly to engage play sessions (just like he did with the puppy), but I just don't know what to do! I worry that he's bored out of his mind, and that it might add to the depression of losing his playmate -- and that this in turn might exacerbate his chewing problems (which I assume have been mostly due to teething so far). I do eventually want to get another playmate for him, but at the moment I can't afford to. Any ideas for how I could entertain him in the meantime -- and possibly help him cope with the loss? Thanks in advance!
