It's common for there to be some tension when introducing a new cat into a household, especially if your existing cat is showing aggression like hissing. It's important to give them both time to adjust and get acquainted.
- Give them time to adapt to each other's presence.
- Ensure each cat has their own space with food, water, and a litter box.
- Use gradual introductions and supervised interactions to help them get along.
Introducing a new cat to your household can be a challenging experience for your current pet. The hissing is a normal reaction to the stress of a new environment and an unfamiliar companion. Begin by keeping them in separate rooms and gradually let them get used to each other’s scents by swapping bedding. After a few days, allow them to interact under supervision, offering treats and praise to encourage positive behavior. With time and patience, your cats can learn to coexist peacefully.
