As you might have seen from the salazzle entry posted shortly after we received this ask (and I do apologize for the delay!), salazzle excrete powerful hormones that attract every male salandit in the vicinity. This is an unconscious act, and it’s basically a survival mechanism. Because female salandit (and by extension, all salazzle) are extremely rare, it’s necessary for a salazzle to be able to make herself as appealing as possible to ensure she breeds and thus perpetuates the species. The fact that males obey her and form a harem around her is part of this survival mechanism as well (not to mention it also explains their behavior towards yours).
Unfortunately, because all of this is inherent in the salandit line, it’s extremely difficult to stop it from happening. You can, however, apply synthetic scents (that is, perfume) to your salazzle to mask her scent and mix with her pheromones in ways that are unpleasant to salandit, but this may be uncomfortable to your salazzle herself. It may be worth trying, however, if her harem is interfering with her day-to-day life with you.
Alternatively, having her lay a nest of eggs typically causes the males to flock towards the nest, rather than towards the mother, as they become far more interested in fertilizing and protecting the eggs at all costs. So, quite literally, allowing her to breed may be another method.
Best of luck, anonymous!
