- Territory stress (new pet, new smell, moving house)
- Fear or pain-related sensitivity
What to do immediately
- Create space and reduce interaction
- Avoid punishment
- Provide a calm safe area
Longer-term support
- Enrichment (vertical space, play routines)
- Predictable feeding and quiet time
- Identify and reduce triggers
