Hello! And thank you for this fascinating question. Cats can breathe faster while purring for various reasons; excitement may be one but pain can certainly be another. At this point, many owners say, 'well I know my cat can't be in pain,' but research studies show that surprisingly few owners identify when cats are in pain; the signs are often not what we'd expect. Thus, until very recently, pain in cats has been underdiagnosed right across the board. I suppose that we all hurt ourselves a little bit, temporarily, sometimes. However, it's worth noting in your diary when (both when in their day, and the date) this is happening and if it is something that you are seeing repeatedly when you didn't before - or if it goes on on one occasion, for a while - then a check up is advisable.
