What are these spots on my Swiss Cheese stem? A bit of a background-I have cats that think my monsteras are a lovely treat. I have 3 stems that have lost their leaves. I’m not sure if it’s because of the cats or maybe fungal? Should I cut this stem off? If I do where should I cut? I attached a photo of where it’s attached with an arrow. There’s an off shoot as well. The rest of the plant looks good.
