Every once in a while a cat for some reason or another will be aggressive, now it all depends on the reason why the cat is aggressive is what makes a difference.
Cats can be aggressive if they are backed into a corner or they feel threatened that is a natural cat instinct. They can act that way with another animal or a human if they feel cornered.
They may act aggressively when they are sick, cats are very independent animals and when they feel sick or they are hurt they act out. This defense mechanism is how they protect themselves. It doesn’t mean they have a behavior problem that requires drastic measures but as they begin to feel better the aggression will dissipate.
Stress is another factor in why a cat may become aggressive. When a cat is under stress from a change in their environment or in the family dynamics they tend to get a bit aggressive.
You may have heard this saying hundreds of times but cats do not like change. Cats hate moving from place to place they don’t adapt quickly to new surroundings so if you feel your cat is more aggressive than normal then try to figure out if anything has changed around them.
Even moving lots of furniture around in the home may cause stress. It's the same furniture but in different areas or rooms. Now the important cat task of sniffing, rubbing on and scenting up to reclaim the "new" items may cause a little frenzied aggression.
Aggression in older cats is common as well, for many of the same reasons why a younger cat would become aggressive as we have mentioned. Other factors in an older cat that would cause aggression would be desensitization and forgetfulness of things familiar to them.
There may be an underlying condition that would cause your cat to become aggressive. For your peace of mind, make an appointment with the vet if you feel your cat is not acting the way she usually does.
