Want to give your dog somewhere to sleep or your cat somewhere to defecate? Perennial Lifehacker favourite IKEA Hacker has a pair of projects designed to make life more comfortable for your cherished pet.
We've featured quite a few IKEA-based litter tray hiding solutions, but the one which Karla has built from the $490 Varde sink cabinet is particularly elaborate, with a separate entry area and "business end". The project requires quite a bit of drilling and messing around, though if you purchased a cat flap rather than building one from scratch as Karla did the work would be a bit simpler.
On the other hand, the dog bed hack proposed by Molly is simplicity itself: stuffing a Ektorp sofa cover (or indeed any suitably sofa or cushion cover) with old clothes to make a bed that's got a comforting "owner smell".
