Apparently Alig got evicted from his apartment and was so hopped up on drugs at that point that he left his 2 cats there. When he finally realized and came back, one cat froze and starved to death and the other was in really bad shape. Ugh, horrible.
To think of those poor cats walking around the apartment, in so much pain and hunger, couldn't get out of the apartment to save themselves, just suffering. I can't even imagine how those poor cats must have felt. How much they suffered. Just awful.
