Feral Cat Characteristics In Trap-Neuter-Return Programs
All groups reported more intact females (53%) than males (44%).
Overall 16% of the female cats were pregnant at the time of surgery.
Pregnancy was highly seasonal and peaked between March and April.
0.4% of cats were euthanized because of debilitating health conditions.
0.4% of cats died during the clinics.
The studies show remarkable similarity between feral groups between various regions.
The results suggest that it is possible to rely on the experiences of existing programs to model new programs.
