This Instructable will show you how to make a cage trap that can be remotely activated. This is ideal for people who practice trap-neuter-release (TNR) to control feral cat populations.
Feral cat colonies are groups of wild, undomesticated cats. Some feral cats and their colonies are a nuisance to restaurants or other businesses. For this reason, some colonies are killed or trapped and euthanized. This is inhumane.
