Yes, cats can remember their people, quite well in fact. I've lived with cats for most of my life and they're quite intelligent and deliberating animals.
As an example, I once babysat (catsat?) two cats for a friend who was on a trip out of the country. He was gone for two years almost exactly. When he returned, the cats recognized him instantly from across the room and literally ran to meet him as soon as he had stepped through the door. These cats were distrustful of strangers--even though they had warmed up to me, they still would not have done that even for me.
So the answer is a very definite "yes".
Yes. Such as if they were abused earlier, they will always remember it. they usually remember Bad things what happened to them or their owner. or it could be the good things that they remember such as getting adopted Dogs have excellent memory.
cats stay with their owner
That period varies and is governed by law in each jurisdiction. You need to check the law in a particular jurisdiction for the time period.
If the hamster hasn't seen you in a long long time then it probably doesn't remember you but don't worry if you do the same stuff you did with it back then, then it might get used to you again.
how to remember
As long as you remember your Authenticator ID you can still log in for a period of time.
No. It is not good to be sad for a long period of time.
A bank lien is usually for a short period of time, but that is only because it instructs the bank to turn the money over to the lienholder within a certain short period of time, usually 30 days. This gives the owner time to go to court to try to get the lien removed. At the end of this short period of time or if the court disagrees with the owner's reason for not turning it over, the bank will send the money to the lienholder.
If you have your ears pierced and you leave them out a long time they will. This is reversible of course, but it involves alot of pain putting you earring in. Remember when you have your earrings in a long period of time always rotate your earrings.
they have a very good memory and if the cat had a bad owner that abused the cat the cat would remember also if the cat had a really nice owner the cat would remember but lets say the cat had an owner that worked full time......and the cat never saw the owner then it would not remember.
A long period of time is commonly referred to as an era or epoch.
