Say hello to ModKat.
The world's smartest looking, most functional
cat litter box
It's got rooftop access and the designers say that your precious pet will enjoy a greater sense of privacy while you'll enjoy a greater sense of cleanliness and smart design. I just don't know if the kittens would really get inside and use it. More details here.
And next..introducing to you the world's first Hamster Shredder. don't be afraid, it doesn't shred hamsters.
Designed by Thomas Ballhatchet, Central St. Martins College of Art and Design, this is a cage in which the hamster, while using it’s wheel, operates a paper shredder to renew bedding. The design made it top ten at the British Council in Milan.
