Lukey and Riley have one from this site - the De Luxe Bastion. It was a bit more expensive than other similar height ones from elsewhere but it's handmade, the posts are solid wood instead of cardboard tubes so it will last much longer and as an added bonus it's not covered in gaudy pawprints

Here it is in action - it's used on a daily basis for sleeping, resting, play fighting, scratching etc etc

Not so active sleeping at the top...

The middle platform

The swing ball...

Now they've grown it's not quite big enough for them both to sleep (comfortably) on the top platform but that doesn't stop them trying!

The tunnel containing a full grown Riley (he is a very big boy too!)
