Carnivores have a predominantly meat diet. As such their digestive system is very different to humans or kangaroos.
Often you’ll see dogs eating grass, vegetables or fruit. Although they can eat this, their digestive system is designed for a predominantly for meat.
They have a caecum, however is much smaller that in other animals
If we look at a wolves skull (picture to the left) we notice their teeth are different to a herbivores. While herbivores grind and chew their food, carnivores must bite and rip their food off.
Another difference is that herbivores chew side to side, where as carnivores chomp up and down.
Unlike humans, their saliva does not contain digestive enzymes.
Carnivores will have a shorter digestive tract. This is because meat is dense in nutrients and they can extract these nutrients easier.
The actual size of a carnivore stomach is significantly large than herbivores. Their stomachs encompass roughly 60 to 70% of their digestive tracts.
Within their stomachs they have powerful digestive enzymes. They have roughly 10 times the mount of hydrochloric acid in their stomachs than humans or herbivores.
