As many of you have experienced, once you start getting hoards of pigs, butterflies, and chickens in your pens, it can become quite a task to properly love each one.
My proposal is to introduce a new craftable powder along the same likes as Fecundity and Shrine powder that will essentially "pet" or "hug" or "massage" all animals on a street. Perhaps mild could give the equivilant of 1 pet, and extreme 2. Something along those lines.
I don't care about the name, but I was thinking "Love potion #3" and "Love potion #7" (primes!) might be appropriate :)
