  3. Cats • Domesticated for at least 5,000 years. • Domestic cat brain is of particular interest. • represents a stage of development between lower mammalian forms & primates • extensively mapped - anatomically & functionally This is my cat Albert. He tried to help with this study aid by bringing me rodent samples and voicing his opinion about how to care for rodents. He thinks he’s very smart.

  4. Handling & Restraint • Minimal restraint a general rule • Transport in mobile cages or carriers • Restraint: • Place 1 hand on neck & firmly secure scruff. • Lift & place other hand beneath hindquarters. • Slide hand under hindquarters toward hind legs. • Encircle hind legs w/ thumb & middle finger. • Place index finger between 2 hind limbs to prevent them from being squeezed together. • Hold upright, close to chest for support, facing away from handler.

  5. Handling & Restraint II • For additional restraint, hold forelegs by one hand. • The other hand holds scruff of neck & controls head. • Protect handlers against uncooperative cats w/ heavy gloves or a thick towel. • Towel over head & body quiets a difficult cat. • Apply least amount of restraint possible to reduce stress.
