I am not paying for the cremation of an animal i killed.
Why do you think people will not accuse you of animal abuse?
I have been reading a good amount about animal abuse on the internet.
Accidents happen but  you should be more careful to make sure that you don't hurt an animal. They could belong to somebody and it would cause them a lot of pain to lose a pet.
I don't care about their feelings it was my fault and I won't pay for it.
Animal abuse is something that our society does not take very lightly, so be careful to not make anyone upset by doing something like this. In addition to that, simply think about the feelings of the animal as well.
