A cat’s resting respiratory rate shouldn’t go over 30 or 35 breaths per minute, anything above this should be checked by your Veterinarian. As a Nurse you will know that the respiratory rate may change in response to pain, oxygenation of blood, cardiac output as well as other factors; there are no specific diagnoses which list rapid breathing as their only symptom as other symptoms may not be observable including anaemia, heart conditions (possibly a murmur) etc… Regards Dr Callum Turner DVM

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.
Also known as dirofilariasis, heartworm disease (HW) is a serious parasitic infection caused by the nematode Dirofilaria immitis which lives in the pulmonary arteries, lungs, and hearts of cats. Heartworms are a type of roundworm, with adult heartworms reaching a length of 12 to 30 cm. Microfilaria (baby heartworms) are present in the blood of an infected animal (in most cases, a dog), when a female mosquito feeds on the blood, microfilaria are also ingested, once, inside the gut of the mosquito, they undergo further development before migrating to the labium (a part of the mouth) of the mosquito. When the infected mosquito feeds on another host (in this case, your cat), the larvae move from the mouthpart and onto the skin of the cat (or dog), from there, they enter the bloodstream via the bite wound left behind by the mosquito.
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.
Currently, most authentic Chausies produced are late generation cats with fully domestic temperaments. Their TICA registration certificates will usually indicate that they are "C" generation or "SBT," which nearly always means they are four generations or more beyond the jungle cat (F. chaus). In cases where they are "A" or "B" generation, it is usually because they have been recently outcrossed to another domestic breed to improve specific cosmetic traits, but the cats are nonetheless more than four generations beyond the handful of nondomestic ancestors.
Sorry to hear your kitty is scratching like that! Does he show any signs of skin infections, fleas, mites, wounds from other cats? The cone could have stressed him further, yes, if he was scratching already because of tension/anxiety. Open sores can get infected, especially when left untreated and scratched further. We would recommend taking your kitty to the vet for a diagnosis. They will be able to provide you the advice and medication your kitty might need. Best wishes!
