He makes it so she can't talk.

"I know for a fact that you're not a squealer," he said with a chuckle. I felt the collar buzz around my throat. I knew what that meant, but tried to plead with him anyway. All that came out were meows. "And I know for sure that you're not a writer," he said, laughing louder. I found out what he meant a moment later when the gloves curled up, folding my hands into fists. The phone was **** out my hands as they were curled into useless balls, but I could hear him laughing as it fell. "I'll be seeing you, Ms. Bell. I have several interested parties that could use their own cat girl lined up for when you get out. Toodles."

I could only meow panicked at the phone as it shorted out. Self-destructed, so as not to link it to Belli. I pulled savagely on the tail, bracing myself against the security door. I tried everything I could think of, including gnawing on it like a wild animal, but nothing was working.
