Here's what I know:
* Cats may urinate outside the litter box for various reasons: Stress, anxiety, medical issues, and changes in the home environment are common causes.
* Getting a puppy can be a stressful event for a cat: The arrival of a new pet can disrupt a cat's routine and territory, leading to stress and anxiety.
* There are ways to help your cat adjust to a new puppy: Providing separate spaces, introducing them gradually, and offering positive reinforcement can help.
If your cat is peeing outside the litter box, it's important to consult a veterinarian to rule out any medical issues. They can also offer advice on how to help your cat adjust to the new puppy.
