TL;DR: Eating dirt (pica) can indicate nutritional deficiencies or stress, and it is potentially dangerous if the soil contains toxic fertilizers or plants. Seek immediate veterinary care if your cat is vomiting, lethargic, or has pale gums.
Why is my cat eating soil or dirt?
- Pica behavior often caused by boredom or stress
- Nutritional deficiencies such as anemia or a lack of specific vitamins and minerals
- Underlying metabolic diseases
How urgent is it if my cat eats dirt?
- Soil may contain toxic fertilizers, pesticides, or potting mix additives like perlite
- Many common houseplants mixed with soil are poisonous to cats
- Immediate veterinary attention is required if your cat is lethargic, vomiting, or has pale gums
How does taking a photo of the plant and soil help with triage?

Clinical Context (Merck Veterinary Manual)
Cats may ingest non-nutritive substances, including natural materials such as wool or cotton, synthetic fabrics, plastic, rubber, paper, or cardboard. Medical problems must be excluded, as they can be responsible for similar signs. If medical problems have been excluded or treated and the problem persists, behavioral history should be examined.
