Causes of pica in cats:
1. If the cat is too stressed, anxious, or bored, it may cause pica. The owner needs to accompany it more and play with it more to relieve its bad mood.
2. If the cat suffers from neurological diseases or rabies, it will also lead to pica. The owner should take the cat to the pet hospital to find out the specific cause and provide symptomatic treatment.
3. If the cat is malnourished for a long time, resulting in a lack of trace elements and pica behavior, the owner should adjust the cat's diet and feed it more nutritious food.
4. If there are parasites in the cat's body, it may produce some toxins or irritations, causing a stress reaction, which may also cause the cat to develop pica. The owner must deworm the cat regularly.
5. Cats especially like to explore new things, and they will nibble on certain objects when they are curious about them.
