A

rabbit: very small thoracic cavity - most of body is abdominal cavity. heart sits ventrally and is cranial and is proportionally quite large in comparison to dogs and cats
guinea pig: similar to rabbit
Ferrets: not hindgut fermenters so have longer thoracic cavity. heart is quite caudal
Birrd: heart is top of hourglass figure in VD rads
tortoise: hard to see anatomy in rads due to shell –> can see in lungs in some views
snakeL have air sacs, identifty heart location by either watching for pulses or doppler
beardy: heart easily visible cranially, dont have air sacs

where do you take blood from small mammals (not rabbits)

A

vena cava: looking for thoracic inlet and between clavicle and first rib should be a dip –> insert needle and point slightly towards opposite hip. if dont get flash right away, dont go deeper and move needle side to side until hit vena cava.
must be familiar with anatomy of different species (ferret has caudal heart guinea has cranial)
