The ASPCA believes that responsible care includes nutritious, species-appropriate food and clean water; basic veterinary care including vaccinations and parasite control; necessary grooming; exercise; social interaction; diligence in identifying and eliminating hazardous substances and situations [see position statements on the use of taste-aversive additives to antifreeze, and on dog chews/treats]; prompt treatment for illness or injury; and, in the case of dogs, cats, ferrets and rabbits, sterilization before puberty. Depending on species, responsible care also requires the use of collars and identification. [See position statement on microchips.]
