One-time project partnership
Barcelona Port: Proof of Concept. Target: 50 sterilisations now, preventing an estimated 300+ future births within 3 years.
How can we know that ?
Based on standard feline reproductive rates where one female can produce 12-15 surviving offspring in 36 months, and assuming a mixed population, we use a conservative estimate of 6-10 prevented births per sterilised animal to account for males and population density factors.
