A friend moved to Ireland 2 years ago with her collection of pets. One of them, a ginger cat, has taken to peeing in her bed, the other pets bed and the owners chairs.
The cat has been through quite a bit of trauma since arriving there.
Its upset and confused. If it is an old cat it may be going senile - yes they do !
If it is a young cat then it may just need some gentle retraining - try keeping it in one small room or animal crate with a litter tray for a week - yes it is hard but persevere a cat rarely pees inits own bed - failing that try asking a vet for some behaviour therapy/guidance. Good luck
Perhaps it's just ginger cats. We used to have a ginger cat who used to do this on the dining room table. Gross. I put him out the cat flap one day and he never came back.
