Since January, Tabby the cat has returned to her family's home in Canada five times with a square patch of fur shaved from her body. The family is mystified, and when they told neighbors about it, one of the neighbors reported that his four-year-old cat Twilight has received similar treatment.
People have also suggested that it may be that Tabby is ripping her own hair out, or perhaps it's pesticides being used on neighbouring lawns that cause her hair to shed, but Yarjau thinks those theories aren't sound, based on the precision and meticulousness of the hair loss.
"It's a pretty clean shave," she said. "They did a pretty good job holding my cat down. It must've been, like, a two man job."
Pesticide or self-grooming also wouldn't explain the cut nipples discovered after this most recent experience.
Yarjau also feels whoever is doing it must get some kind of sick pleasure out of it.
