Sunburns
Please take action and prevent direct sunlight from entering your home if you own one of these very easily burned cats. Since they don't have any pigmentation or fur they burn very eaisly. Slap some baby sunscreen on their ears and and nose, even on their skin to help prevent burns.
A good way to prevent your sphynx from receiving a burn in your home is to install sun screens on your windows -they usually just snap right in without a struggle and are available at most hardware stores such Home Depot or Lowe's. Rarely you will find a pet store or two that carries them, but I suggest hitting up the hardware first and see what they have in stock.
