4. Check if She Is Under Stress

Stress can mess senior cat’s life. Be it environmental stress or emotional senior cats are prone to both.

Sudden change in the environment or her routine can give her stress and in severe cases, it can also develop FLUTD.

Stress can become the root cause of many diseases. There are several reasons your old cat can come under stress like

  • Absence of her favorite hooman in the house
  • Loud noises
  • New pet in the house
  • New member in your family
  • If you have shifted to a new house.

The reason is that felines are territorial and don’t like to share the litter box if another cat or stray cat has already marked her territory in that.

There are higher chances that your old cat may feel threatened by other younger cats, and she may not go inside the litter box to pee, and hence, she will pee outside.
