I got a 2 years old female abyssin cat 1 week ago.
all day long until about 22h00 she is like a glue ball, always following me, rubbing on my legs, jumping on my laps and purring non stop.

After 22h00 she is a monster, hissing all the time. even if im about to give her food, then she gets excited, she sneeze and hiss.

If she get afraid and cover under my bed and I go there, she will attack me.

But worse, When I touch her litterbox to clean it, she gets totally crazy and scream like crazy... VERY VERY VERY loudly

Is this normal? will she get rid of this behavior with time?
