The litter box should always be clean at all times and placed in an optimal location. Scoop out the waste daily and change the litter box twice a week or more if you have the time. Place the litter box in a low foot traffic area and not anywhere near where you feed him. If you’re not too fond on litter boxes you can train your Foreign Blue to use a spare toilet, which is as good as any litter box in the market.
Rapid breathing (tachypnea) is a respiratory disorder characterised by abnormal breathing that is rapid and shallow.  It is caused by a reduced level of oxygen, mechanical disorders (where the lungs aren’t able to expand as they should, usually due to a build-up of fluid in or around the lungs), and physiological disorders in which the cat’s respiratory centre in the brain is over stimulated.
