Cats peeing on the bed may want to mark their bed with scent or take revenge on their owners. Many cats will urinate indiscriminately when they are in heat, especially male cats. This phenomenon also occurs in individual female cats. When the owner finds that the cat urinates on the bed, he should clean and replace the sheets with new ones in time to prevent the cat from urinating in the same place next time. The owner can also perform sterilization surgery on the cat. If the cat urinates due to revenge on the owner, the owner can coax the cat with the snacks it likes to eat.
