Suffused with the powers of both cat and girl, Ben was mostly just confused about why this alien was included in the Omnitrix. She didn’t really seem to be able to do anything out of the norm. It did feel awfully relaxing to have the sun on his fur. Ben quickly shifted to a new Alien, but took a mental note to revisit the odd cat lady when things weren’t so hectic.

It would soon turn into his favorite form of relaxation, shifting into the alien he now called “Cattress” whenever he got the chance. Napping in sunbeams became a daily ritual, to the point where his cousin Gwen got concerned.

Ben offered to let Gwen join him, and after a bit of convincing she wound up joining him dozing away on sleepy afternoons. Ben had finally figured out what the alien was for: Just having a nice nap and sometimes that’s the only power you need.

There were some side effects of Ben’s prolonged exposure to Cattress. After a few weeks spent dozing off as Cattress during his downtime Ben found a rude awakening after one of his naps. Shifting back into himself and after a trip to the bathroom he quickly realized he was now a girl. Initially, Ben hid the change from his family, figuring he’d go back to normal after not using Cattress for a while.

Thankfully, he didn’t really look or sound all that different as a girl so Ben found it pretty easy to hide. It probably would have even worked had Gwen not gotten accustomed to their naps. She pestered Ben until he broke, shifting himself into Cattress once more so she’d stop bothering him for a while. He forgot how nice it felt resting in the sun, the warm rays heating up his fur as the scenery flew by. He really began to appreciate how their catnaps had led to Ben and Gwen becoming closer as well; they’d chat about their other family members, their friends. Cattress’s body purred in contentment as she dozed off to sleep.

This time Ben woke up from being Cattress with a tail. Ben decided he might as well come clean about his recent change in gender as well. Grandpa Max just rubbed his temple and sighed. He thought the whole nap obsession thing was kind of weird but ultimately harmless; now he would have to explain to his kids not only a new daughter, but one with a tail. Max made Ben promise not to use the form anymore, as it was clearly too dangerous and hopefully the changes would wear off in time. Ben eagerly agreed; being Cattress was a nice vacation but winding up stuck as a cat girl wasn’t really something he was too keen on.

Ben found his new tail fairly responsive and managed to hide it by wrapping it around his waist and putting a jacket on top. He could only hide for a few hours though, the longer he kept his tail wrapped up the more cramped and sore it would feel. Gwen would occasionally tease him about being a girl, but was ultimately supportive of her cousin; she even offered to share clothes.

Ben kept to the promise he made to Max, but unfortunately for him the Omnitrix had other ideas. Every so often the device would glitch out, forcing him into the body of Cattress. Each time, he’d come back to find himself further transformed into whatever alien Cattress was. First, his ears changed. Then fur started popping up. His eyes became slitted, his feet became paws, and his hands grew sharp claws. He started to develop a bit of a muzzle, and his teeth became sharp and pointed.

Eventually he came to the point where the only thing that changed with becoming Cattress was his fur color and his age. Max relented on the Cattress ban seeing as it couldn’t get any worse. Ben went back to spending his free time lounging around as Cattress, who was basically himself but older. As Ben gradually began to see himself as a girl, his other Aliens began to show up as female as well.
