There are no specific health problems related to the Russian Blue. It is a genetically sound breed, mainly due to it being a naturally occurring breed. Brushing the coat is not essential, but is a nice addition to the weekly routine of other grooming, such as brushing the teeth. This breed has a particular fondness for human company and will sit quite happily while being combed or brushed, since it is spending time with the one it cares for.
If Mya started panting after playing suddenly, that may be a sign that something might be wrong. If is has been hotter than normal, and suddenly, that might explain the panting. It is difficult to say without the ultrasound whether she has a problem or not, unfortunately. She seems quite healthy otherwise, but if the panting is a dramatic change, having the ultrasound will let you know what is going on with her.
My fiance said the he saw her eat this afternoon, so that is a relief. Her gums are pink (that's one of the first things I looked at on her and I should've told you that...but... this is my BABY CAT and she has me a little panicked!.. not like dealing with humans on the ambulance... she's innocent!) I do have access to oxygen... so we can make her an oxygen tent if it's necessary. Right now, she is getting up every couple of minutes and repositioning or pacing.. her respiration rate is around 50 right now... her belly almost looks like it's spasming and her heart rate is running between 80 and 90 everytime we take it... which is low... what do you suggest??????
