Russian Blues have a tolerant nature toward children who treat them kindly and respectfully. They will even put up with the clumsy pats given by toddlers, as if they recognize that no harm is meant, and if necessary they will walk away or climb out of reach to escape being bonked on the head. That said, the patient and gentle Russian Blue should always be protected from rough treatment, so always supervise very young children when they want to pet the cat.
Thank you for your email, I'm sorry that Cracker is having these problems. Without examining him, it is hard for me to advise you on whether he is suffering, and that is probably a question to ask the most recent veterinarian that you took him to. If he has a fungal or bacterial infection, he should be improving on those medications. If he has cancer, he may not improve, and it is important to assess his quality of life. If he starts breathing with his mouth open or stretching his neck to breathe, that is serious respiratory distress and is an emergency. IF he is eating and drinking and generally happy, he may be breathing heavier but not suffering. It would be best to have a recheck with the most recent veterinarian, as it has been a week on medications, and see if they feel he is improving - they may want to take x-rays and compare them with the previous x-rays to look for signs of improvement. They will be able to give you a better idea as to whether he may be suffering, or if he seems comfortable. I hope that all goes well with him.
There are various different causes for rapid breathing which may include infections, pain, heart disorders, dehydration among other causes; a cat’s respiration should be below 30 breaths per minute when at rest but if it is significantly above this rate at rest I would suggest visiting your Veterinarian for an examination to determine a cause.
