I stumbled across this cat condo on eBay - I thought the price was pretty good compared to most I've seen (even after shipping - especially within Canada), so I went ahead and ordered one. I hope eBay links are allowed

FYI this merchant also sells on Amazon.ca, but their current eBay price is much cheaper, at least for this particular item. I hope my cats like it!
