We understand that reason, but if you do this, please arrange for it to see a vet. It needs neutering, injections and antibiotic treatment. This is what the welfare agencies do, and why we suggested taking it to one. Otherwise it will breed more homeless cats, which increases the number of diseased population, which in turn is cruel to all animals. It is also not learning to scavenge at an early age and relying on humans. Healthy feral cats are very good at surviving.
I have had animals all my life.
