Surfer is not only an animal lover, but a cat lover. Why would he lie about something that was clearly difficult for him to repeat? I wish I could find the clip of PPP talking about this on stream years back. Godwinson also confirmed the cat story, but he isn't a reliable source.
I watched live when Surfer dropped the cat story, KC was on at the same time. The KC chat was flooded with "PPP KILLED A CAT." Anyone who had NOT killed a cat would be beyond confused and horrified seeing that fill their chat out of nowhere. PPP barely flinched, showed absolutely no shock, and instead of denying it simply said "well Surfer jerked off an alpaca." Surfer worked on a farm and collecting semen to sell for breeding purposes was part of the job, hardly the same as sodomizing a cat to death with an iron rod. My point is, PPP had next to no reaction to, out of the blue, being accused of sodomizing a cat to death. What does that tell you?
