The Nova Scotia SPCA laid charges of animal cruelty that relate to confining an animal to an inadequate enclosure, unsanitary conditions, inadequate ventilation and not providing an opportunity for exercise.
Cruelty investigators removed the animals from the house last week and took them to various shelters in Nova Scotia.
The shelters estimate the intake will cost more than $15,000 and they are asking for donations.
The cats are being spayed or neutered, tested for feline leukemia, dewormed, vaccinated and socialized.
The SPCA says they will be available for adoption in the coming days.
