i am basicaly roleplaying, not going into detail,

does anybody know a house with a smaller building outside to use as a "kennel" for a clanfear?

Yes. But for that you have to play, not basically, but in full detail Morrowind!!

Depends on what you're looking for--do you want one with an interior cell, like a regular loading door, or do you want an area that's still an exterior?
Skaal Village, for example, has that outside pen--if you could sneak one past the guards, he might be okay in there.
You could Command a Clannfear with you to the pen, casting Calm Humanoid on any upset guards who might try to kill it. I'm not sure if he'll live much longer after that, guards tend to kill anything in the creature category.
If you really want this clannfear around guards and people, you could just go into the CS, make your own clannfear, and tick his box off as humanoid. That should prevent anyone from trying to kill it.

i know how to get the clanfear, soultrap summon glitch, just need a suitable house

That summon glitch was a nightmare on my xbox, it constantly locked up & crashed.

I'm not really sure what you want for a "kennel" - are you just looking for a neighboring house, next to your own?
Just grab any two houses in a town, then. Command Humanoid on the inside occupants, lead them outside. If the spell successfully wears off, they stay outside. Their home is yours.

Or you could just go into the CS and build your own-I'm sure you could make a nifty-looking kennel area. Are you on PC?

xbox sadly
