Jealousy is not just a human trait; our pets feel it acutely too. Life overwhelms us with responsibilities and we don't get to spend as much time as we would like with our pets. And then, pets tend to get moody and feel jealous.

"There is ample evidence that pets become emotionally attached to their owners, as seen in the distress they exhibit when owners leave them alone and the grief behavior that is sometimes observed when owners die," per Aeon. "Owners of pets report that the degree of jealousy they observe in cats and dogs varies with how much the cats and dogs like their owners. This observation might also explain why people think dogs are more jealous than cats since generally, dogs are more attached to their owners than cats are," per a SAGE Journals article. No matter what the study says, both felines and canines exhibited jealous behavior when their owners were busy with something else or when a third person (or creature) came into their lives.
