is a disease that is common in many mammals. Some of its forms are considered congenital and appear immediately, while others develop with age. Gradually progressive blindness affects the outer surface of the retina. Specifically, this form of the disease is characteristic of Bengal cats. Doctors call this disease progressive retinal atrophy.
The disease affects photoreceptors. They register the incoming light flux on the retina. Photoreceptor cells begin to break down at the age of 8 weeks, and by about a year the animal completely loses sight. You can notice the signs of the disease in the period from 8 to 20 weeks.
SIGNS OF THE DISEASE
It is possible to detect hereditary blindness in a Bengal cat by external phenomena. Continue reading
Since 1980, the University of California has conducted a study of immunity and susceptibility to leukemia in wild cats. Subjects in particular were Asian Leopard Cat (ALC). Jane Mill (surname after her second husband) received for work several hybrid F1 females (first generation ACL and domestic cats of various breeds). She brought the ideal groom from India in 1982. At the New Delhi Zoo, the breeder was shown a small spotted kitten hiding next to a rhino. He was unusually good: dark brown clear spots evenly covered the golden-orange shining fur. Jane has never seen such a shiny, but sparkling coat – this effect has never been seen in domestic cats.
The fact that the cat named Delhi (full name when registering CFAMillwood Tory of Delhi) did not have a tail bothered the scientist only at the beginning of the experiment – he was not genetically tailless. Continue reading
Jane Mill and a Bengal cat In the early 1960s at the University of California (USA), a study was conducted of the immunity of representatives of the cat family. Among the wards were both large cats – lions, tigers, leopards, and their small brothers, including Felis bengalensis. Little Asian leopards lived together with other domestic cats, resulting in kittens born from female Felis bengalensis and a black shorthair cat. Then one of the daughters was tied up with her father and got lovely spotted babies.
Research continued, and in the course of it continued numerous breeding of Felis bengalensis with American domestic cats. Jane Mill took part in these experiments, who decided to create a new breed of cats and in the 1970s took 8 females – first-generation hybrids. Initially, she added two cats to this group: a spotted one from a Los Angeles shelter and a domestic cat with orange eyes and juicy brown rosettes from the Delhi Zoo. Continue reading
