Why is it that cats and dogs can eat dirty food, meaining they
eat leftover food from humans and eat food that is thrown on the
ground, containing their saliva which have germs, bacteria etc and
yet they do not fall sick whereas if human beings are to eat such
type of food, they will fall sick?
hi xunni
there are some truths behind why cats fall sick after eating
human food, most of the time it is because they are a different
species of animal which possess a digestive system that
has a different set of enzymes which allow them to only break
down the food which is suitable for their species, they are in
the process of dying a slow death from eating human types of food
by our ignorance, you may also see over-obese cats is also a sign
of inefficient digestive properties due to wrong food.
similarly, when cats
contract illnesses and die, it is oni those viruses and bacteria
that find the cat's body conducive will survive in it and reproduce
and affect the cat. what affects the cat may not affect the
human, and what affects the human may not affect the cat. but
still, cats are like humans to protect itself from new foreign
bodies and with it's self-immunity, it can deal with certain
illnesses itself and recover from it.
thus, an old cat who was
fed with human food tainted with cough viruses may be infected and
never recover from the illness compared to a younger one. a
pregnant cat which is healthy enough to take in human left-over
food may unwittingly pass virulent disease that mutates and attacks
the kittens in the womb which can lead to the deformed kittens
