The SPCA in Sydney, Cape Breton has so many cats there's a waiting list for people who want to give their animals to the organization.
The SPCA built more holding rooms for the felines, but those quickly filled up. They have more than 100 cats already that are available for adoption.
"We have a waiting list right now of over 150 people that are waiting to surrender their cats," said Lori MacMullin, the chair of the Cape Breton SPCA.
The shelter has a no-kill policy. MacMullin said they send about six cats a week to the Halifax SPCA, but now that shelter is also near capacity.
"We try not to turn any animal away, however we'd like people to try to understand and work with us in this situation," she said. "If they can hold the animal for a certain period of time until we have the space to take it, we do appreciate it."
The Sydney shelter does have some available space for dogs.
MacMullin said the situation would improve if pet owners would have their animals spayed or neutered.
