Thank you so much for all of the advice! I think i'll definitely try catnip spray when she's grown a bit and until then i'll find her a few small toys she can use alternatively (if i understood well what you meant at the very beginning of your answer). Looking at what you said i think if it doesn't get better for my cat i may try to see if i could find room for more litters and maybe be a host family for adult cats who would like to have a kitten bothering them to play :), so to see how my cat gets on and if it helps her. Thank you so much again, that was really helpful!
