It’s a well-known fact: cats multiply at a very high rate. An unsterilized female can give birth to three litters of at least four kittens every year. After four years, over 20,000 cats may descend from the original mother cat. The “Trap-Neuter-Release-Maintain” (TNRM) method is a humane, effective and low-cost way to keep the number of street cats down. The method involves trapping, sterilizing and, if necessary, vaccinating and deworming adult cats living in outdoor colonies. These cats, which are feral or semi-feral and therefore not suitable for adoption, are then reintegrated into their environments, where their number gradually decreases thanks to the reduced reproduction. Adoptable animals will be placed into forever homes.
