Unfortunately, these owls are not being produced anymore so the link doesn't lead anywhere useful. Anyone who still wants one can buy up the rests by the resellers (try googling "Mars&More tweed owl" or similar). I think there's still a few Terrys and Levis to be bought, e.g. on Amazon.

Jkadlubo also found a cheaper spinoff with somewhat different design on a Polish interior decor website, so there's that.

[Edit: or contact me and I'll help you find one if I can.]
