They are most likely growling
A shaking cat should be checked by a vet. Shaking like this could range from seizers, nerve damage from being hit by a car, hypothermia from being out in the elements, rabies can cause shaking as it attacks the nervous system, or even distemper.
Put what on the cat? This question is incomplete so is impossible to answer.
The rat being the prey of the cat would , naturally , be eaten particularly if the cat is hungry .
she is rather sick and dizzy, and may fall over
The word cat translates to gato or gata in Portuguese, the former being the masculine noun, while the latter being the feminine.They are pronounced GAH-too and GAH-tuh, respectively.
The cat would eat the gecko, then freeze to death. If the cat swallowed the gecko hole, it would be warm for a while but later die.
You should laugh!!
Normally you would hear a hissing sound accompanied by your cat being angry
It depends if your cat likes being on a leash. If not walking your cat around the yard would be more like following the cat. If you held it that would be a different thing. You wouldn't exactly be "walking" your cat.
You DON'T. The cat is acting on instinct. The cat would not understand why she was being punished, because cats don't reason the way humans do. She would just think you were being mean, and would become afraid of you and maybe bite and scratch you.
Take your cat to the vets immediately! This could not possibly be diagnosed correctly or efficiently here.
Depends on which species of mammal you're thinking of. A bear - being an omnivore, all-eater - would happily eat seeds while a cat - being a carnivore, meat eater - wouldn't be able to.
