Hello. Yesterday evening our beloved cat passed away, he was 9.5 years old. He grew up with my son. Smart, calm, not clingy, but very affectionate to his own, especially to me. A big white fluffy ball of fur. Died unexpectedly, got sick two days ago and that's it. Kidney + heart defect. In the hospital for a day they were giving him injections, trying to help - it didn't work. I understand that it's just a cat, I try to stay calm, but sometimes tears come. Then the baby starts kicking, obviously also grieving. :( I worry about him, but I can't hold back the sadness. Did you have such a period during your pregnancy
