Why does your cat act nice one minute and nasty the next?

Answer 1

Cats personalities come from several things: if you get a cat from the pound, it has likely been traumatized early in life. this is not good. it means the cat has gotten a bad feeling about life from and early age. this means they are likely to be more cautious or sometimes, if the traumatization was very bad, mean and defensive. this would occur because they already had a bad experience with humans and think they are all bad. if your cat is raised by a nice mother, then it is likely to be more playful, confident and pleasant around humans because, being young, it has no reason to hate or fear humans. other, more specific personalities come from genetics and tiny differences and how the individual cat is raised.

Answer 2

If you mean they're acting strange, like ornery, then maybe they got traumatized on one of their outings. Unless your cat never goes outside. Maybe you traumatized him. Did you just get another cat? If so, that's probably it. Cats don't like new cats encroaching on their territory.

Answer 3

Cats can be pretty funny creatures, but there is a method to the madness. First of all, cats sleep for the majority of the day (sometimes close to 20 hours) so, for the few hours that they are awake they have A LOT of excess energy to burn. Which is why, when you are sound asleep at 3:00am, your cat may suddenly decide it needs to run laps around your house at mach 10, stop suddenly and pretend like nothing happened, and then do the same thing again, but this time counter-clockwise. It is also why cats engage in a number of odd behaviors during the day. Another reason that cat's act "strange" is that they are practicing their predatory skills. An activity that may look very odd to you (like jumping from the floor to a 4ft high banister, stopping on a dime and then sitting there for a minute before jumping back down) may very well be your cat honing it's hunting and survival skills (this is also why they will make an obstacle course out of various parts of your house and run it a few times in a row before settling down to a nice cat nap). As to why cats sometimes knead, (when they look like they're running in place if they are de-clawed or when the pull at the carpet, a blanket or your tummy if they have claws) this is a vestige of when they were kittens and were still nursing. In order to get more milk from a mother cat kittens will knead the area around her teat while they are suckling. This helps the flow of milk to the teat and enables them to consume more. Once cats grow up they sometimes still do this just as a comfort activity, perhaps it reminds them of mom.

There could be any number of reasons. We wouldn't be able to guess why. What you need to do is rule out that there is something medically wrong. If there isn't, then check for any changes around the house - new pet, new room mate, new furniture or rugs, change in food, etc.
