Your pet loves you—no doubt about it. But what happens when they think someone else is stealing your attention? Cue the dramatic stares, the sudden mischief, and maybe even a stolen sock or two. Jealousy isn’t just a human emotion; our furry (and feathered) friends feel it too.
From dogs wedging themselves between you and your partner to cats giving the coldest shoulder in history, pets have their own ways of saying, “Hey, remember me?” Even birds, rabbits, and reptiles can throw a little attitude when they feel left out.
So, what triggers this possessive behavior, and how can you handle it without hurting their feelings? We’re breaking down 22 pets that show jealousy—plus the best ways to keep peace in your multi-species household. Because, let’s face it, life’s too short for a rivalry between your dog and your new houseplant.
Dog

Dogs are pack animals, and jealousy often arises when they feel their place in the pack is threatened. When another pet or even a person receives more attention, a dog might display signs of jealousy such as whining or pushing themselves between you and the other pet.
It’s crucial to recognize these behaviors early and address them. Spend individual time with your dog, reinforcing their importance in the family. Training and providing consistent affection can help alleviate their jealousy, ensuring they feel loved and secure.
Cat

Cats may appear aloof, but they can be surprisingly sensitive to changes in attention. If a new pet or baby enters the scene, a cat might act out through scratching or ignoring the litter box.
To manage feline jealousy, maintain a routine and provide plenty of playtime. Cats thrive on consistency, so keep their feeding and play schedules steady. Offer affection and reassurance, ensuring they know they’re still a cherished part of the family.
Parrot

Parrots are highly social and intelligent. They may develop jealousy if they perceive another bird or person getting more attention. Signs include loud squawking or feather plucking.
Addressing this involves ensuring your parrot gets plenty of interaction and mental stimulation. Rotate toys regularly and engage them with new tricks, ensuring their environment is enriching and full of variety. Your attentive care can quell feelings of jealousy, reinforcing their place in your heart.
Rabbit

Rabbits can become jealous if they feel neglected or replaced. They might act out by thumping or refusing to eat.
To manage jealousy, maintain close bonds with your rabbit through regular grooming and affection. Providing them with toys and a stable environment helps mitigate jealousy. Ensure they feel included, and their place in your life is secure.
Hamster

Hamsters, though solitary, can show jealousy through biting or cage bar chewing. This often happens when another pet becomes the center of attention.
Combat this by spending quality time with your hamster. Regular handling and enrichment activities can prevent jealousy. Personal attention helps them feel valued, ensuring a harmonious coexistence with other pets.
Goldfish

Goldfish are not commonly associated with jealousy, but they can exhibit stress-related behaviors when tank mates are favored. Signs include erratic swimming or loss of appetite.
To minimize this, distribute feeding evenly and ensure all fish have ample space and hiding spots. Balanced attention and a well-maintained environment can help reduce stress and promote well-being among your aquatic friends.
Guinea Pig

Guinea pigs form strong bonds and may act out if one receives more attention than another. They might squeak loudly or nibble to express jealousy.
To manage this, ensure each guinea pig gets individual time with you. Setting up separate playtimes or petting sessions can ease tensions. Recognize their social nature and foster a loving environment where each feels cherished.
Ferret

Ferrets are curious creatures that can become jealous if not the center of attention. They might nip or hide belongings to express their feelings.
Regular play sessions and interactive toys can help prevent jealousy in ferrets. Establish a routine that includes quality time with them, ensuring they feel engaged and appreciated. A dynamic environment keeps their spirits high and jealousy at bay.
Horse

Horses are social animals and can show jealousy if another horse gets more attention or treats. They might display this through nipping or refusing commands.

Budgerigar

Budgerigars, or budgies, are sociable birds that can feel slighted if others receive more interaction. They might screech or become less vocal.
To address this, engage your budgie with interactive toys and dedicate time to socializing. Ensuring they have a stimulating environment and feel part of the household can alleviate feelings of jealousy.
Chinchilla

Chinchillas, though independent, can experience jealousy, especially with new pets. They may show this through distancing or erratic behavior.
To prevent this, maintain a consistent routine and provide ample playtime with your chinchilla. A variety of toys and a rich environment help keep them content. Reassurance through gentle handling can reinforce their place in your home.
Canary

Canaries, often quiet, can become withdrawn if overshadowed by other birds. They might sing less or become lethargic.
To manage this, ensure your canary receives enough attention and stimulation. Interactive toys and varied perches can enhance their environment. Regular engagement and affection solidify their bond with you, minimizing jealousy.
Rat

Rats are social creatures and can become envious if a cage mate receives more attention. They might exhibit jealousy through biting or neglecting play.
To manage jealousy, allocate individual time for each rat. Regular handling and affection help reinforce their bond with you. Providing a varied and engaging environment ensures all rats feel valued and content.
Pony

Ponies, like horses, are sensitive to the attention given to others. They might act out through stubbornness or ignoring commands when jealous.
To manage these feelings, make sure each pony gets individual time and attention. Grooming, feeding, and engaging in bonding activities help alleviate jealousy. Building a strong rapport with your pony ensures they feel appreciated and secure.
Lizard

Lizards may not show jealousy like mammals, but they can become stressed if attention shifts. Signs include refusal to eat or lethargy.
