Kari Poore, executive director of the SPCA-Animal Rescue League, is reacting to a council decision Monday to remove cats from animal control coverage.
The city has offered the group a one-year animal control contract, but Poore says the contract does not include cats.
Poore says cats multiply at a rapid rate, noting the group's shelter took in 1,600 cats last year.
She says if that many strays are left on the streets, another 10,000 cats could soon be on the loose this year.
As well, she says more foxes and coyotes could move into the city to feed on the larger cat population.
