I came accross neutering serum in the State Store. Are there any benefits to neutering a pet?

Neutering a pet means it can no longer breed. You can breed a pet a couple times, decide you don't want to breed it anymore and then neuter it. A lot of long-time breeders sell neutered pets from a specific bloodline/gene pool but don't want that specific set of genes to become too common. I sell neutered Symurghs from my Sky Raider line, since Salt of the Earth perfect symurgh are one of my prize gene combos.

Oh, I get it now.

Thank you!
