I adopted a cat from a shelter and they didn’t disclose the cat had Feline Leukemia Virus (a very aggressive virus that transmits to cats and similar animals via nasal droplets. Like a mix of Covid and HIV for your kitty). Brought her home and was met by my and my then-gf’s other three cats. All four of them were dead within a couple years.

Shelter did not take responsibility, denied the cat I adopted had it when she was at the shelter. No payout, gf broke up with me because according to her, I indirectly killed her babies
