That's exactly like Jack & Sunny, I bought an igloo more for Sunny as she can be shy, but she's used it about 10 times in a year!
So I usually resist the teptation to buy a big activity centre or bed as deep down I know they'd rather be sat on us on the sofa and Jack in particular would rather be on my lap pawing his favourite jumper till it falls apart
Cats really are the rulers of the world
