My very first job (before I was diagnosed with any mental health conditions) was always horrible to me and one day when she knew my cat was seriously ill (my very first cat) she made a nasty comment about "let that thing die", then the day my girl Beauty died I went into work really upset (she was due to be euthanised as soon as I finished work) my boss said she was glad Beauty was going to die.

She hated cats and didn't keep her hatred of cats to herself.
