My little sister 12 stepped on our less than a month kitten today. I think her rib is broken, she can’t walk, can’t do anything. I’m trying to reason with my parents to talk to a vet but they don’t care and it’s really hurting my feelings. I wish I could do it on my own I really feel sad. They don’t wanna take responsibility for it. I don’t have the money to do it myself, I’ll feel so bad if she dies
