Why does my hyper cat calm down when wearing a jumper? Is it safe?

Updated On September 23rd, 2025

Pet's info: Cat | British Shorthair | Female | spayed | 1 year and 7 months old

Not sure whether this is health related but just asking in case i’m doing something wrong. My cat is very hyper, however, when i put her jumper on her she goes straight to sleep and calms down straight away. Is the jumper bad for her?

No, I wouldn't say the jumper is bad for Mars. It could be that she has some anxiety, and that comes out as being very hyper. When you put the jumper on her, the close contact of it makes her feel safer, thus leading to the calming down. There is an item called a Thundershirt that is used for dogs and cats with anxiety, and it is reported to do that same thing in that calms down dogs and cats when upset. The jumper likely has the same effect on Mars. It's fine to use it on her. I hope this helps!
