Hideaway Strath Schlammschlacht.

His mind ran back in time, feeling the hardness of his cage, the sounds of dogs barking, the other animals in the large room. Some were large and brayed hideously, some clucked and squawked. There was a large black cat too. They were unlikely friends, he thought. They couldn't talk, but they knew how to communicate. They used their eyes and paws, he guesses a little like Ptero, but in their own way.

"Dead animal. Their old skin without fur." Leather. He didn't know how they managed to do it, but it made him gag. Torture. Not even being able to yawn properly.
"It went tight around your muzzle and strapped around behind your head." It locked you in place and there was no way to get out. He'd tried everything but he had limited space. The black feline had been there longer, she knew not to struggle. 
He swallowed thickly, glancing away.
