Four of the five species of the big cats (the Panthera genus – lion, tiger, leopard, jaguar and snow leopard), the exception being the snow leopard can hybridize with each other to produce numerous hybrids. In fact, breeding of two different pantheras to produce hybrid big cats has been banned in many zoos and animal sanctuaries due to no conservation value of the hybrid, and the risk it poses on the mother that gives birth to it.
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
Cat fanciers may think that Russian Blues only have blue coating, but this isn’t always the case. In other cat associations such as New Zealand and Australia, the term “Russians” can be applied to black and white varieties, alongside the traditional blues. Even the U.S. Cat Fanciers Association and TICA allows black-colored Russians or Russian Whites into play in provisional cases.

Blood transfusion for acutely anemic cats or cats who have suffered significant blood loss or kittens who have neonatal isoerythrolysis. Blood typing must be carried out before a blood transfusion. Cats have three blood types, Type A, Type B and Type AB.  Type A cats can only receive type A blood, Type B cats can only receive type B blood, and Type AB cats can receive blood from type AB blood or type A blood.

If Shadow is having trouble breathing whilst laying on his back, it may be attributable to a few different issues, but head position and the soft palate can cause a restriction in the airway which may cause some breathing difficulty; at your next visit to your Veterinarian ask them to check his throat and soft palate for any issues.

Pyothorax (pleural empyema) is the presence of pus in the pleural space in the chest cavity, the thin, fluid-filled space that lies between the lungs and the chest wall. Any pathogenic organism can cause pyothorax including fungal, viral, bacterial or protozoal; however, a bacterial infection is by far the most common pathogen. The collection of pus is due to dead white blood cells and dead bacteria. Common bacteria involved in pyothorax include Pasteurella spp (the most common), Nocardia spp,  Streptococcus spp, Clostridium spp, Proteus spp, Bacteroides spp and Mycoplasma spp.
Much like her Siamese relative, the Russian blue is very vocal, and she'll use her voice to communicate with her pet parents when she wants to play, eat, or snuggle. She's both observant and persistent, always ensuring that her needs are met. She doesn't adapt well to change, such as varying meal times or unknown visitors, so expect to hear about it! She'll respond positively if you converse back-and-forth with her on a regular basis, which means you're never truly alone when you have a Russian blue fur baby.
Two days is still early days for treatment but you should start seeing some improvement in the next day or so, I would say to give it the weekend and if there is no improvement in Jinx’s condition you should return to your Veterinarian on Monday for another examination. Improvement in an animal's condition, especially with antibiotics, can be delayed in most cases so unless your Veterinarian said specifically ‘you’ll see improvement over the next 24 hours’ or something similar you should give it three or four days at least.

Causes for an increase in respiratory rate may include pain, infections, heart disease, respiratory tract obstruction, increased temperature among others; a cat’s resting respiratory rate shouldn’t be higher than around 40 breaths per minute, if it is higher than this then I would advise you visit your Veterinarian for an examination to determine the underlying cause. Regards Dr Callum Turner DVM


The Russian blue is a sweet-tempered, loyal cat who will follow her owner everywhere, so don't be surprised if she greets you at the front door! While she has a tendency to attach to one pet parent in particular, she demonstrates affection with her whole family and demands it in return. It's said that Russian blues train their owners rather than the owners training them, a legend that's been proven true time and again.
Lots of places claim to be breeding cats to save them from extinction when in fact they are not involved in any real conservation effort and rather are justifying their breeding to have babies who will bring in paying visitors and worse yet to sell.  Many people contact us each week saying they want to start a captive breeding program to save the cats from extinction, but the only viable programs currently being operated in such a manner as to accommodate this goal are being run by accredited zoos who will not work with the private sector.  Unless you can trace your cat’s pedigree all the way back to the wild and you have been accepted into the Species Survival Plan for that specific breed, you will not be aiding conservation, but rather will be contributing to the over abundance of unwanted animals.
My cat has feline viral rhinotracheitis. The vet has given him steroid shots as a temporary fix but it doesn’t help much. Today I came in my house and found him breathing very hard and labored. His respiratory rate is 120, yes 120. His ears are very warm and his third eyelids are covering half of both eyes. He won’t eat. He will not respond to me when I talk to him. He has been on my sofa asleep all day.
If you’re her favorite human, be ready for nonstop love, because she is all about you, you and more you. Feeling out of sorts? She’ll stick by your side, working her healing abilities on you until you’re up and at ’em again! Prepping dinner? She’ll chill by your side, acting as taste tester. Binge-watching a new TV show? She’ll curl up by your side — just have a comb handy, as she loves being brushed while watching the tube!
Okay so we’ve had our cat since being a kitten and she’s always been very scatty as we think she was abused, due to getting her and her having marks on her neck, but her breathing has always been rapid. (80 resps per minute) but in herself, she’s like any normal cat. She’s very friendly, not in any form of pain, is this something that needs to be addressed?

So, my cat has been breathing fast for the last two days. She has been eating, drinking water and peeing/pooping normally as it seems... We had a big clean up in the house and all of us (humans and cats) were sneezing for a while so that is one of the possibilities, I guess...The other thing is that we had the sand of the sand box changed to one with a smell so maybe that was giving her allergies or something... These are two possibilities but I'm still worried. Do you think I should be concerned?
Queening is a painful process just like childbirth is for humans and some heavy breathing or panting may occur afterwards for a few days due to discomfort. But if you feel that she is straining or in distress you should visit your Veterinarian to check her over to ensure that there isn’t a retained kitten or another issue leading to these symptoms.
