While searching the house in Stuttgart in relation with a different case, police found 104 rabbits, two guinea pigs and two budgies, many of them living in transport boxes.
"This happens all the time with cats and dogs, but I've never heard of a case like this with someone hoarding rabbits," a police spokesman told The Local.
Officials had to take help from local vets, who took the animals away to a shelter.
Why the man was keeping so many animals in his flat is being investigated. The authorities may bring legal action against him for mistreating the creatures.
