my street cat uses me

she is very friendly but the thing is she is an extremely horny cat, she gets knocked up every 5 months and gives birth and then gets knocked up within 2 weeks again.

this is fine i dont judge her but the thing is she always comes to me when she is pregnant and i take care of her with my whole heart only for her to vanish and never return when she finally gives birth :( i can only imagine how her kitties look like
