Why is my cat suddenly hissing at other cats after our trip?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 15 lbs

My cat has been hissing at my other cats a lot recently after we went away for the weekend and before we left she would cuddle with and play with them just fine. Do you know any reasons she would suddenly start hissing at them after we went away for the weekend?

It's possible the stress of your being gone caused the behavior change. I would give Hippy a few days to rest, relax, and make sure she can get to her food, litter, places to hide, etc without being bothered and see if that helps. Sometimes, pain or underlying illness can also cause a cat to suddenly lash out and hiss or swat at other cats, so if the behavior continues or you see visible signs of illness, a vet visit to rule out health issues is best.
