A kitten turned up in my family's yard. Because of her tanish-grey coloring and the black tufts on her ears, we at first wondered if she was a bobcat kitten. A quick look at bobcat traits (she has a long black tail, no ruff of fur around her face) proved that not to be true, and we figured she was just a slightly odd-looking stray domestic cat. We took her in.
If your cat is breathing heavily while resting, it can be a sign of several common problems from anxiety to airway disease. Understanding some of the reasons for labored breathing in cats can help you assess the severity of the situation. However, if your cat is having difficulty breathing, this is an emergency, and you should take your cat to your veterinarian right away.
Thank you for you email. unfortunately, without examining Kai, i can't comment on what might be going on with him. He needs to see his veterinarian to try and determine what is going on with him and how to treat him. If he seems to be in distress and unable to catch his breath, taking him to the emergency clinic tonight is most appropriate. I hope that he is okay.
