Yes, animals may not often display their emotions, or human beings may not exactly see when different animals are showing their emotions, but according to studies, they are capable of experiencing a different range of emotions. It is normal for them to feel happy or sad from time to time.
There will also be instances when they may show anxiety because of various reasons. For example, there are some cats that may become anxious whenever a new pet is being introduced to the rest of the household. It may start licking itself too much, which is a known sign of insecurity. A lot of animals are also known to show some signs of loneliness.

Yes, animals have emotions. Non-human animals are able to express a range of emotions such as happiness, sadness, anger, grief, anxiety, curiosity, and fear. If you watch animals closely, you will know how they respond to situations they find themselves in. Feelings of optimism and pessimism can also be seen in a wide range of animals.
If an animal is in danger, you can tell that they are frightened. When everything is good, animals can be playful and happy. Animals can be aggressive, shy, bold, relaxed. Animals can show empathy; they can protect one another from harm. However, we cannot tell if animals are capable of expressing complex emotions such as jealousy and contempt, as seen in humans.
