I posted about my cat not using the litter box to poop before. (she only use it to pee).
It got better after I get a second litter box. I found out that if there's pee-spot in the litter, she will not use it to poop. BUT if there's a poop in the litter, she'll still use it to pee.
It's like so mindf***ing. And she doesn't like the bigger litter box. I figured out that it's the location but my house is small and I can't afford to put it somewhere else.
SHE STILL POOPS OUTSIDE THE BOX for no reason at times, and because theres pee spot most of the time. I can't afford to clean it 24/7 because I have class sometimes (the whole day until night).
Oh and she also doesn't poop in the box if I ignore her for too long or I don't have time to sayang her.
=/ I am at the verge of giving up in training her to use the litter box.
p/s: and i found out that she doesn't know how to 'cover' her dirty jobs in the litter. Unlike other cats, she doesn't even dig the litter sand. She just go up and go down like it never happened.
help please?

I live in flat too but i never put anything except recently a collar with a tag incase my mom accidentally let her out and forgot to let her come in (she'll only linger at the front door and will come in very quickly).
Is it like really necessary to put on a harness and leash to avoid her from jumping out?? My cat doesn't seem to want to escape at all

but i can be wrong
it is up to you, my house has open space where we hang the washed clothes, i cannot afford to make grill and cannot afford to lose my cats. if u feel your house is safe then it is up to u.
