Pet houses can be various: futuristic, minimalist and functional or like this – funny and cool. ThinkGeek presents pet houses in the shape of sharks. The entrance to the house is through the shark’s mouth to the belly. The piece is made with nanotechnologies, so that the house is self-cleaning. The fabric absorbs the smells and different bacteria. All you need to do is to put the parts of the house in the sunlight and it will be clean. Cushions and other fabric parts may be washed; there are different sizes to choose – both for cats and dogs. With such a sleeping house your pet would be happy!
