Do bigger things decay faster than smaller things?

Question

For example, would a human decay as fast as a cat or fox?
We are trying to decide if zombie cats have a shorter than zombie humans.

Also if you know, does the solanum (zombie virus) have the ability to infect animals or just humans?

Answer 1

Solanum is a virus only if it is in a living zombie. This is
a paranormal area. If you were buried for 1000 years and some
shock forced your activization to get up and walk, the actual
distance would be in the chemical compositions or radons
that had entered the dead skeletons head, That is what a
solanum virus would be in order for someone, or animal to
get infected. It is not as uncommon as some might think.
Animals generally do not carry any of it to cause infections.
This is in a total phenomenom area if you were in a graveyard
at midnite and were brushed by the activation of a spirit that
moved to a different location, generally it is called a heart
shock and in the worst case, say you got lost also, you could
become so frightened that you had a reaction where this
spirit thought you were its new home. Bodies decay in some
ratio according to the interactions of their lives, is the spirit
issue you found here, laziness, ugliness, severe retardation
would have a much higher likelihood of getting these viruses.
This is related to radio transmission of thought materials of
dreamers, travellers, prayer makers, and diviners. The grave
has got rules and how the minerals are cleaned from bodies.
In inanimate objects like boulders they do decay more rapidly
because of the magnet center being identified by the receptor
more easily(compared to stones).

Answer 2

Decay has to do only with physical conditions:
1-Tempreture of the area is proportional to the decay rate(that's why mammothin the snow didnt decay)
2-amount of oragnisms(specifically microorganism) present at the dead body.
3-surface area: yes logically if at the same conditions,a human would decay and become a skeleton slower than a cat,yet ofcourse quicker than an elephant.

P.S Zombies dont exist,stop watching resident evil!!
