They don't know what the actual time is, any more than you would without a watch. Like we do, we know it is day and night and roughly the time of year by the seasons, amount of daylight, weather etc. That is all they or even we need to know. It is only the human world that works on specific times for appointments etc.
Without same intelligence level/emotional capacity as humans, animals cannot perceive time in the same way
this would be hard to prove, but surely all animals will feel pain or ail sometimes in their life time
to make the animals happy
Yes, they feel fear.
yes
Animals are only harmless if they don't feel threatened or feel in danger,if they feel that they are in danger then they protect themselves by warning you and if you don't listen and go away they will attack you.
they can if they are not asleep
terrible!
like animal..
When they feel like it. :/
It would depend on which animal. If it has a brain, it can "feel" in one way or another. Animals with no brain like coral cannot feel, but they do react to negative stimuli as all living things do.
yes they are because they feel the same way we do and animals are always there when people are not.
