Rats are very good breeding machines, so that they can do something called post partem extras. So essentially every month, most species of rebnent can have another litter of young well, dt, you o, they're just puming em out. A lot of people sa why we're just going to stop them having babies. We want to get rid of em. And so a lot of it is trying to make people understand that actually this is much more sustainable,. more humane for starters, but actually is more ecologically sustainable than trying to kill them.
