Pascal was a problem cat. He'd been in a shelter for nearly six months with no adoptions but he was so beautiful and obviously needed a loving home. I decided to try. Sometimes he was loving and affectionate. Sometimes he was playful and funny. But sometimes he was aggressive and he frequently bit me. Hard. Deep. I have lasting scars. I tried everything I could think of. Pheromones, drugs, even a therapist. Nothing was effective, so I finally had to let him go. But I will always love him.
