Now that the success of the shampoo has been proven, it was time to expand the congregation. There were more alligators that had been flushed down into the sewers, though being apex predators, they weren't always in big groups. But there were always plenty of homeless people, though not always in the sewers.
But if anything improved with the change into anthro gator, it was hunting skills. The humanoid gators and the feral gators they've dominated combed through the sewers, looking for more alligators and humans to transform. When alligators were caught, it usually took a short fight to make them submit. The humans were sometimes easy to persuade as they had nothing left on the surface and being a powerful humanoid reptile had appeal. Of course, some people were more opposed to the idea, having more self-respect than to just abandon their humanity. Some humans called the gator men demons and signs of the end times, though they were just nutters whose addled-minded nature lead to them becoming homeless in the first place. The shampoo usually cleared their minds as the alligator instincts stabilized them.
The transformations became almost ritualistic. Two humans scrubbed a feral alligator until all three became an even blend of mammal and reptile. The reason it took two humans per gator to create such a balanced form was most likely because the gator had at least their combined mass on its own. Theoretically, a smaller alligator would only need one human for them both to become anthros, but as of yet, there weren't any alligators small enough to try.
The humans above had no idea what was going on below their feet. They could care less about what happened to the exotic pets they flush or the hobos who weren't on the streets. What had started as a congregation of 9 gator men had swollen to 60. The gender ration was roughly even, though each new transformation could tilt it one way or another. Their numbers were certain to keep increasing in time, especially after the clutches of eggs start hatching.
