Hello, I am desperately asking for advice ... I have a one-year-old cat, adopted from the rescue station at 4 months and at 8 months when she started grunting, neutered and living in an apartment. Hereinafter referred to as Darkness. She was always very active and playful. But lately he's been really aggressive ... When I asked my neighbor for temporary babysitting for 4 days, she didn't even approach the lady for 2 days and then she started behaving very aggressively, until it was necessary to wear gloves. When I returned, everything was fine. Unfortunately, today the lady scratched her neighbor's face ugly, scratched, scratched, bitten and meowed ... she was also very aggressive in the presence of another person. When we're alone, it's perfectly fine ... That's why I'd like to ask if anyone has any advice on what to do with the little devil ... I'd really like to find a solution.
