Why has one of my 10-year-old female cats started hissing at the other out of nowhere? Should I be concerned?

Lately, one of my 10-year-old female cats has begun hissing at her sister, something she's never done before. This behavior seemed to pop up out of nowhere, and it's got me a little worried since they've always been best buddies. Could there be something wrong with her, or is this just an age-related change in behavior? Should I possibly separate them to prevent any escalation?

Answer

It's concerning when a previously friendly cat begins hissing at her sibling. This sudden change could indicate underlying health or environmental issues, rather than just age-related behavior.

  • Monitor for any signs of illness or injury.
  • Consider recent changes in the household or environment.
  • Seek professional advice if the behavior persists.

Your cat's behavior might indicate something physical, like pain or illness, or it could be stress-related due to a change in their environment or routine. Cats are sensitive creatures, and even small changes can trigger reactions. Consider any alterations in their environment or recent stressors and watch for signs of discomfort or illness. Separating them temporarily could help prevent escalation, but it’s essential to address any underlying issues.
