First: stray cats have nothing to eat, and they will be forced to kill some foods that they don't usually eat.

In fact, it is difficult for stray cats to get cat food. They can only find food to fill their stomachs in the natural environment, and some stray cats will be forced to catch birds to eat. Moreover, cats have a strong predation ability, which can be seen when cats catch mice. In addition, stray cats will become a little extreme because of long-term hunger. In the process of catching birds, it can't control itself.

As long as all the birds appear in the sight of stray cats, stray cats will arrest them all, and stray cats will not leave them alive. Then once this happens, it is likely that stray cats will destroy the entire ecosystem. Birds have been unable to control the number of insects in this system, so it is likely to cause damage to the whole ecosystem.

Second: stray cats will become extremely sensitive because of many injuries.

Stray cats usually escape after being abandoned or abused. Because these browsing hairs have been hurt by many humans, they will become very sensitive to changes in the external environment, and stray cats will also become irritable. They will disguise themselves badly to prevent being hurt, but often these stray cats will have a feeling of throwing caution to the wind.

Whether human or animal, if there is no fear, it is the most ferocious. Therefore, the stray cat will suddenly become a different person, no longer a docile kitten, and seems to have the shadow of a tiger, whether it is being contested by the same kind of people or bullied by dogs. So don't provoke stray cats, because no one can predict what this stray cat will do.

It is likely that he was seriously scratched by a stray cat's paw during the interaction with him. This injury is still terrible.
