Here's why:
* They are solitary animals: Fat-tailed geckos are primarily solitary creatures, only coming together for mating.
* Breeding season: They have a distinct breeding season, typically during the warmer months.
* Multiple mates: During breeding season, females may mate with multiple males.
* No parental care: Unlike some other lizard species, fat-tailed geckos don't exhibit any parental care.
Therefore, while they form temporary bonds for the purpose of reproduction, it's not accurate to say they mate for life.
