rabbits and guinea pigs
require continuous movement of food through the gut to maintain intestinal motility and BG

Question 3

rabbits have high atropinase enzymes

Answer 3

rapid breakdown and lack of effect of atropine

anaesthetic physiological challanges

Answer 4

high surface area/BWT ratio
high metabolic rates

Question 5

small size and high metabolic rates

Answer 5

high O2 consumption
high metabolism
prone to hypothermia

pre anaesthetic exam

Answer 6

HR
temp
RR
coat condition
fecal output
BCS
