Did your parents give you any indication why they would do that? Did they tell you they couldn't look after your cat? That's pretty nasty of them, I would be so upset if my Mum did that. My aunty did that to her kid a couple of times when he got pets cause he was spoilt and she couldnt say no but he was spoilt and he wouldn't take care of it and neither would she. So sad.

Hugs and prayers to you in your hard time. It is awful losing a loved pet.
