Many of these cats are not neutered, and unwanted kittens are sometimes dumped in nearby bushland, where they mature, breed, and boost the feral population.
Suur osa neist kassidest pole aga steriliseeritud ning paljud kassipojad, keda kellelegi vaja pole, viiakse kuskile kodulähedasse metsa, kus nad üles kasvavad ning paljunema hakkavad.
