She starts hissing out the blue then she poops
It sounds like your cat is experiencing some stress or anxiety, especially with the recent change in household members. Cats can be quite sensitive to changes in their environment, and this can sometimes result in behaviors like aggression or inappropriate elimination.
When a cat hisses and then defecates, it can be a sign of fear or extreme stress.
Firstly, create a quiet, safe space for your cat where she can retreat and feel secure. This could be a separate room equipped with her bed, litter box, food, and water.
Ensure that the litter box is clean and placed in a quiet, accessible location. Sometimes, adding an extra litter box can be beneficial, especially if there are multiple cats or if she feels threatened in certain areas.
If the new household members are causing stress, try to gradually introduce them to your cat. Allow her to approach them on her own terms and provide positive reinforcement when she does.
Effects may vary depending on your cat's personality, current condition, species, etc. Keep an eye on her behavior. If the aggression and inappropriate elimination continue or worsen, it might be helpful to consult with a feline behaviorist. They can provide more tailored advice.
If you have any further questions, please feel free to ask. Thank you.
