Feline compulsive disorder is a condition characterized by repetitive, purposeless behaviors that the cat cannot stop. Common examples include excessive grooming, pica (eating non-food items), and tail-chasing.


When to Seek Immediate Veterinary Care
Immediate veterinary care is necessary if your pet develops skin wounds or hair loss, ingests a foreign object leading to vomiting or decreased appetite, or exhibits uncontrollable behavior that escalates to self-harm. Even when symptoms appear to be behavioral issues, they may stem from underlying medical conditions such as hyperthyroidism or neurological disorders, so it is essential to rule out physical health problems first.




Medication Requires a Veterinarian’s Prescription
If environmental enrichment and behavior modification do not lead to improvement within 4 to 8 weeks, or if the behavior has escalated to self-harm, your veterinarian may consider prescribing fluoxetine or clomipramine. The dosage of these medications varies depending on your pet’s weight and overall condition, and using human medications without veterinary guidance can be fatal. Therefore, it is essential to have your pet diagnosed by a veterinarian and receive a proper prescription.
