The cat on the left was well known as the Cobweb Panther in the 1980s. This unique feline was sold from the Dublin zoo to the Glasgow zoo where it became well recognized. The director of the Glasgow Zoo, Richard O’Grady, was sure that this particular black panther had a new color mutation. O’Grady also pointed out that the Cobweb Panther’s gums were strangely pink. While the cat was 10 or 11 when she came to his zoo and black furred animals are known to get smatterings of grey or silver hair in their old age, he had said that he had seen the cat in its youth and the grey markings were remained unchanged throughout her life. She gave birth to two litters which did not inherit her coloration. It is assumed that, on top of
melanism, this cat had some other gene mutation.
