Cats can suffer from depression. Factors such as changes in environment, their relationship with their owners, and the arrival of a new pet can cause depression in cats. Symptoms of feline depression include decreased appetite, reluctance to move, and increased irritability. Feline depression is often accompanied by other complications, so it's recommended to take your cat to the vet as soon as symptoms appear. Therefore, as a cat owner, in addition to taking good care of your feline companion, don't neglect spending time with them. Pay close attention to any unusual behavior in your cat to prevent depression. 
Symptoms of feline depression:
1. Marking territory. When a new cat comes to the house, it may feel uneasy and stressed, so it may spray urine in the room to mark its territory.
2. Spending excessive time hiding oneself. Cats are social animals and have a favorite hiding place, such as a dresser drawer or closet. However, spending excessively long periods hiding oneself can be a sign of depression.
3. Cats also experience stress, and some cats with high stress levels will excessively lick their fur, often licking and chewing it all off, which is a sign of depression.
4. When a cat suffers from depression, its personality will change drastically, and it will be prone to anger. Playing with the cat may upset it, and it may even scratch people.
