Why is my senior cat lethargic and sleeping more after new guests?

Updated On September 23rd, 2025

Pet's info: Cat | British Shorthair | Female | spayed | 15 years and 1 month old | 15 lbs

Hello, Our femaile cat, Stella, 15 years old, has just recently become very lethargic, only wants to eat dry food but drinks water ok. She is mainly an indoor cat but even when out prefers to be around us in the garden. Recently our pregnant daughter & her partner have had to come to live with us (temporarily) & we are wondering if this might have had an effect on Stella as she no longer has the run of all the rooms in the house! She just seems to sleep all day or at least rest & not move about.

It is very possible that the change in household is causing Stella a bit of stress, and thus her behavioral changes. Pain or illness can also cause cats to change behavior some, so ruling out any health issues, especially since she is a senior lady, is a good first step anyway. if she checks out healthy, making things as inviting as possible for her by adding in some extra perches she can watch people from, places to hide, spending more time together, and even a pheromone diffuser such as Comfort Zone can help make the transition a little less stressful and may help her return to a normal routine.
