To maintain an outdoor cat's health, prioritize clean, accessible water, proper nutrition through fresh kibble, and shelter that protects from harsh weather, utilizing insulated totes for emergency refuge. Transitioning to indoor living enhances safety and health, facilitated with engaging toys and treats. Essential veterinary care includes microchipping, sterilization, up-to-date vaccinations, and regular check-ups to prevent parasites and diseases, more crucial for outdoor cats due to increased exposure to environmental risks. These steps ensure a healthy, happy life for feline companions.
