Local police in the town of Sant Antoni de Portmany on the west coast of Ibiza have reported a woman to the town council for owning over 100 pets.
According to sources from the local council quoted in Spanish daily 20 minutos, police, along with environment officers, visited the house last week where they discovered the estimated 70 dogs and 30 cats.
The inspection was carried out along with a vet, who certified that the animals were all in a good state.
According to neighbours the animals were strays, picked up off the street by the woman who then looked after them.
Soon, neigbours began making complaints about the noisy cats and dogs, as well as the stench that was produced by so many animals living under one roof.
Out of the 100 or so animals in the house, only three had a vaccination card and chip, which are obligatory for all domestic pets in Spain.
But, the council admitted, all the animals were in relatively good shape, apart from a few overweight felines.
If the animals were in good shape, the house was not, it was not properly weather proofed and was, unsurprisingly, covered in animal excrement.
The local town hall is talking the necessary steps to get the animals vaccinated and, according to 20 minutos, will find alternative homes for them if necessary.
The woman was still a way of making the Guinness World Record for the most cats. That is held by Jack and Donna Wright of Kingston, Ontario in Canada, who at one point, lived with 689 cats.
