question : do u not live alone ?
or did u urself ever feed tha cat ?
cats do this, when they have learned, where and how to get food.
someone in your family feeds the cat (?)
basic conditioning.
if not, then this might simply be transferred knowlage, from the cat having learned that she reaches her goal ( getting food ) somewhere else.
what would i do :
condition her aversively.
maybe connect the trigger conditioning even with another triggger ( e.g. a bell ), to later more comfortably trigger the aversive action.
( u will soon understand what i mean )
so here is the plan :
what cats absolutely dont like, ist getting sprayed with water.
so if u have a gerdenhose : why to go.
will take several repetition, tll cat will associate that house with the aversive stimuli.
to make recognition and triggering the memory of the aversive stimuli ( water ) easier accessible, i would ring a bell everytime i spray/hose the cat.
aver several repetitions/days, u will only have to ring the bell, and cat will piss off asap.
then some sonner, she wont even come near the house at all.
should work pretty reliable.
( alternatively u could also chose the cuckk way of 'dealing' with the cat : feed har. shell instantly shut up.
problem : this totally enforces her behaviour and u will never ever get rid of her again, untill u like hose her every day for 3 years in a row every day, lol . this option is not recommended (at all)).
