I just want to know if it's possible that philodendron could've been the cause of my cat's death. I left town for five days, leaving my roommates to care for my two cats. When I returned, Bri (my now dead cat) was crying in pain. I immediately took her to the vet. He took blood and told me to wait until tommorow for the results before treating. She had a thickening in the abdomen he said, but there was no blockage. That night Bri was silent and still with her head on the floor (like sleeping in a very uncomfortable position). She responded very minimally and would occasionally walk a few steps to sit in a different spot. Her eyes were not blinking very much. She did not eat or drink. She urinated on the floor from the IV (given at the vet earlier). I noticed at that time my roommates had brought a philodendron and peace lily into the house. The next morning she was worse looking, moaning and looking dead. The vet said she was having a stroke with seizure like leg movements. Her blood pressure was high. She stayed in his care on oxygen. A couple of hours later her heart stopped and he couldn't revive her. Did the philodendron do this to her?
