To know for sure you’ll need to see the pedigree and your cat should have been registered with a cat association. A pedigree is a family tree going back four years or more that contains the full names of the cats, all of which should be Russian Blues or cat breeds that are approved for breeding Russian Blues by the cat association. That sounds awfully complicated but all purebred cat cats are registered in that way in the West (Europe and North America). There are a number of cat associations. Hope this helps.
My wonderful kitty Dave is generally very healthy. He cuddles and plays all the time and is always by my side when I’m home. I’ve noticed this a few times but most recently a few days ago- he’ll be breathing very fast (60bpm) and shivering. He doesn’t try to hide and definitely wants to be held or cuddled but doesn’t want to move around. Last time it happened there was a bad thunderstorm and I wasn’t home for the worst part of it. Could he have just been scared? After a little while as the storm does down, he used his litter box and peed a lot, then pooped - also a lot. Buried it. Drank his water, ate some food and was back to purring and playing. I can’t remember if it had stormed the other times he’s acted like that with the rapid breathing and dilated glassy eyes, but i did notice that he’ll cuddle then use the box and feel better. He’s even cried before in his litter box, like it hurt to go poop. But I figured out that only happened when he ate fishy cat food so now he gets beef, chicken or turkey.
Getting a Russian Blue cat is no light matter if you’re serious about having one in the house. The best breeders are the ones that are the most established in their region; they won’t easily give you a Foreign Blue until they know that you’re a good candidate for it. For starters, it will be best to meet the kitten’s mom and dad and check for pedigree and overall health and well-being. Allow the breeder to ask you several questions to make sure you and the cat breed will be compatible living together.
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.
