I have to ask this question as our Ophelia has a bit of a thing about the bits of tetra pak that come off the top of packets of Bozita. The boys both play with traditional cat toys, leather tassels, mice on a string, laser pointer etc. She's never really shown much more than a "OOHHH thats exciting... i'm bored now" interest in those. But the tops of these packets she'll play with for ages. We knew she liked them but not quite how much until yesterday she was trying to get at something under one of our armchairs. I lifted it up to find about 20 of the things under there like some kind of shrine she's made. So what non standard things has your cat made into the most exciting thing in the world?
