No, you can't adopt this clan. But, you can get a cat from it. 

This clan is. . . . PathClan

Basically, any cat that has been killed on the Thunder Path or by any other man-made thing, or killed by humans in some way, joins PathClan when they die.

It is called PathClan because. . .

1. Most of the cats in it have been killed by the ThunderPath

2. The cats in this clan have lost their way, and have gone to a different path. Which means, they wanted more in life and they definitely wanted to die in a better way than at the cruel hands of the Twolegs. Now, they roam on a path of hatred and suffering, wishing they had made different choices that might've saved them from their death.

This clan has an undying leader, the first ever member of PathClan. . . 

LostStar. He is called LostStar because he lost his sight when he was very young. One day, he was separated from his mother and decided to take a drink from the river. The river was poisoned by the Twolegs. The parasites in the water made him go blind over the course of a few moons. He did't die by blindness, though. One day, his smelling was off. He didn't realize that he was on the Thunder Path until it was too late. Now, LostStar paces, "If it weren't for the Twolegs, I never would have gone blind, and there would be no Thunder Path if there were no Twolegs!" he thought. However, he knows there is nothing he can do about it, so he tries to be at peace with who he is.

More members of PathClan coming soon. . . 

However, I need your help. Please give me some ideas for members of PathClan. Thanks!
