Not much is known about this rare breed; however, it is believed that the Russian blue originates from northern Russia, specifically the Archangel Isles. According to the Cat Fanciers' Association (CFA), cat rumor has it that "the Russian blue breed descended from the cats kept by the Russian Czars. Assuming the Russian blue did migrate from northern Russia, it was likely via ship to England and northern Europe in the mid-1860s." As early as the sixteenth century, recorded history shows that trade ships passed between this territory and the British Isles, and the Vikings were active in both regions centuries prior, but there is no mention of the Russian blue cat until the nineteenth century.

Lion coloration is usually orange-brown, with the exception of white lions. The underparts are generally lighter and the tail tuft is black. One of the most distinctive features about lions is that male lions have a large mane, whereas lionesses lack manes. The way to tell the difference between a male and a lioness cub is by looking at their neck; male cubs have small black manes, however, it is more difficult to to tell the difference between a male and female white lion cub.
One important note to keep in mind with this breed is its love of food. It will eat beyond its need and ask for seconds, making it a sure candidate for weight related conditions if it is allowed to eat as much as it wants. The best prevention is measuring the food and giving it only at assigned times of the day, and making sure that everyone in the house knows that they cannot give the cat too many treats or scraps.
If a cat’s resting respiratory rate exceeds 40 breaths per minute you should visit your Veterinarian; there are many causes for an increase in respiratory rate which may include infections, pain, heart disease, liver disease, parasites among many other conditions. Whilst you should keep an eye on her, I would still recommend visiting a Veterinarian sooner rather than later to be on the safe side. Regards Dr Callum Turner DVM
Hello. My cay spooky was hospitalized last night for suspected poisoning from bug spray. He was stabilized and spent the night with iv and vitamins, pain medication etc. Today at around 5 they released him to be watched at home and he seems much better although he seems to be having rapid breaths or a hard time breathing. I can hear it and he seems to be straining. Is this from all the medication or residual poison? will it pass?
A normal healthy cat will take 20-30 regular breaths per minute. The air travels into your cat’s lungs and is used to oxygenate the blood, which is then circulated throughout your cat’s vital organs. When a cat is suffering from rapid breathing, this breath rate increases and often becomes irregular, or shallow. This can often be an indication that your cat is not able to bring enough oxygen into the lungs to supply their body’s need. Rapid breathing is a symptom that can be caused by a number of illnesses or injuries. Since regular breathing is vital, if your cat is suffering from rapid breathing (also known as tachypnea) it is a serious and life threatening condition and you should seek immediate veterinary care.
Cats, both pedigreed and domestic, come in a rainbow of colors and patterns. These are all a matter of genetics, so a calico mother might give birth in one litter to calico, tabby, and solid or bicolored kittens, depending on her genetic background and the background of the male cat(s) that fathered the litter. Cats, come in three basic colors (called "self" by geneticists): red (commonly called "orange," or sometimes affectionately referred to as "ginger," or "marmalade"), black, and white.
The Bengal cat is a considerably older breed than the others in this list, but as a breed derived from a wild cat hybrid, it is worth a look. The Bengal breed, which developed from a cross between a domestic cat and an Asian leopard Cat, is also the starting point for other breeds in this list. There have been stories of naturally occurring crossbreeds in Asia from way back, with the oldest confirmed case in 1934. The breed as we know it began with geneticist Jean Sugden-Mills, who crossed ALCs with domestic cats in 1963. Twenty years of breeding resulted in the breed that was accepted as truly domestic by TICA. Bengal cats are large cats with distinctive markings. Generations F4 and beyond are considered to be good house pets.
My kitten Rupert is only 7 weeks old and he started breathing rapidly the night before. At times he groans and breathes with his mouth open. He feels and sounds most uncomfortable when he is being held, but still has discomfort if laying down for a long time. I'm not sure if he has a cold, or if its something wrong with his lungs? He had just been in the emergency just 2 days ago for low blood sugar, but he wasn't doing this at that time. What do I do?
Smooth, medium wedge, neither long and tapering nor short and massive. Muzzle is blunt, and part of the total wedge, without exaggerated pinch or whisker break. Top of skull long and flat in profile, gently descending to slightly above the eyes, and continuing at a slight downward angle in a straight line to the tip of the nose. Medium in length. Length of top-head should be greater than length of nose. The face is broad across the eyes due to wide eyeset and thick fur. Muzzle smooth, flowing wedge without prominent whisker pads or whisker pinches. Neck long and slender, but appearing short due to thick fur and high placement of shoulder blades.

Points or Pointed Markings: "Points," or darker shades of the body color, generally include the ears, muzzle, tail, and feet of the cat. The original pointed cat was the Siamese, and many years later, the Himalayan was developed by crossing Siamese with Persian cats. Many other breeds of pointed cats are now accepted by cat registries, including Ragdoll, Ragamuffin, Birman, Exotic, Balinese, and Javanese. Breed registries disallow pointed patterns in most other breeds. Many mixed breed cats display these distinctive points, which may be found in various colors.
The first Savannah hybrid was born in 1986 and named Savannah by breeder Judee Frank. That cat's traits inspired Patrick Kelly to team with Joyce Sroufe to develop the breed. A Savannah is the largest of all domestic cats, can leap great distances, and is illegal to own in some states. They are intelligent, curious, and often remind their owners of a dog. The International Cat Association (TICA) recognizes Savannahs as a championship breed. 
After I had a party at my house a few days ago, my cat has been acting very differently. He sleeps all day and only gets up to pee or poop, doesn't eat and drink as much as he used to, and starts breathing more rapidly and heavily. I've brought him to a vet and they said that it's likely due to stress caused by the party, and for the past couple of days I've been giving him liquid food and vitamins with a pipette, but I feel like his breathing has actually gone worse. I'm just afraid that the vet misdiagnosed him (since I live in a rural town in Indonesia, I don't really trust the vet here), so do you think there's something more going on than just stress? Oh and if it helps, my cat had just done his first vaccination about a week ago. Thank you
The Russian Blue stands out for his coat color. To the uninformed, he might look gray, but in cat show terms he is an even, bright blue with silver-tipped hairs that make him seem to glisten. Some Russian Blue kittens are born with “ghost stripes,” a reminder of the tabby gene that all cats carry, even if it isn’t expressed in their coat, but these generally fade, leaving the cat with the solid blue coat of maturity.
The domestic short-haired and domestic long-haired cat types are not breeds, but terms used (with various spellings) in the cat fancy to describe mongrel cats of a general type, by coat length, that do not belong to a particular breed. Some registries permit them to be pedigreed and they have been used as foundation stock in the establishment of some breeds. They should not be confused with standardized breeds with similar names, such as British Shorthair and Oriental Longhair.
Rapid breathing (tachypnea) is a respiratory disorder characterised by abnormal breathing that is rapid and shallow.  It is caused by a reduced level of oxygen, mechanical disorders (where the lungs aren’t able to expand as they should, usually due to a build-up of fluid in or around the lungs), and physiological disorders in which the cat’s respiratory centre in the brain is over stimulated.
Although an immediate improvement in the bloodline was made when Russian Blues were imported from Britain, it would take years to establish the exact type that would personify the Russian Blue. Breeders were breeding traits into their lines based on their own preferences, so that their Blues would be splendid in one area, but never overall. The breed was too varied, with some exhibiting pale, exquisitely plush coats, and others showing elegant bodies, beautifully shaped heads, and striking green eyes.
Lethargy and increased respiratory rate are not specific symptoms as they are shared with many conditions; however I’m concerned that they are a common sign that an animal is in pain, but without examining Marilyn I cannot say whether she is in pain or there is another cause for the symptoms. You should visit your Veterinarian for an examination to be on the safe side especially if this has been going on for a day or more. Regards Dr Callum Turner DVM
