Indoor Palm Bad Odor: Diagnose Source (Rot, Animal, Bloom)

Repotted palms indoors with bad odor. Need details:

• Palm species & age.
• Previous pot size vs. new 14″.
• Odor description (rotten, sweet, ammonia, earthy).
• Any pets (cat urine?).
• Watering routine.

Possible Causes

1. Root rot: Overwatering/large pot → anaerobic decay (rotten smell).
2. Animal deposit: Cat/other in soil (ammonia).
3. Flowering: Some palms have sickly-sweet bloom odor.
4. Soil anaerobiosis: Compacted, waterlogged soil.
