Pet supplies is a multi-billion dollar industry, but one sector of this lucrative market has been ignored for far too long. Sony is aiming to remedy that with its latest line of consumer technology – Animalia.

Animalia is being billed as “Tech for pets.” The first products available include speakers for hamsters, a home theater system for dogs, and best of all – headphones for cats that always look like they’re on.

Like everything else today, this is merely an April Fools’ Day joke, but there is a consumer electronics market for pets. Famous DJ Deadmau5 created a pair of headphones last year that were specifically fitted for his cat.
