Yes, it is possible for your spirit animal to change over time but some people can also have a lifelong connection with their spirit animal. Those that experience a lifelong connection most likely have a more challenging lesson to learn that will require more time with a particular spirit animal. But, keep in mind that it can vary from person to person.
It’s not uncommon to experience shifts or connections with different spirit animals at various stages of your life. As you evolve, learn, and experience different phases of life, your spiritual needs and connections may change, leading to a shift in your spirit animal association. It’s important to remain open and receptive to these shifts and changes for your spiritual growth.
