Siamese cats are known for their social and affectionate nature, and it’s important to help them feel safe and secure in their new home. Here are some tips that may help:

1. Give them a quiet space: Siamese cats can be easily stressed by changes in their environment, so it’s important to give them a quiet and secluded space where they can retreat to when they feel overwhelmed. This can be a small room or a designated area in a larger room, and should be equipped with a bed, toys, and plenty of hiding places.
2. Gradually introduce them to the new environment: Siamese cats may feel intimidated by their new surroundings, so it’s important to gradually introduce them to their new home. Start by keeping them in a single room and gradually allowing them to explore other areas of the house as they become more comfortable.
3. Provide plenty of attention and affection: Siamese cats thrive on human interaction and affection, so be sure to spend plenty of time with your new cat. Pet them, play with them, and provide plenty of positive reinforcement.
4. Establish a routine: Cats are creatures of habit and thrive on routine. Establishing a routine for feeding, playtime, and other activities can help your Siamese cat feel more secure in their new home.
5. Consider using pheromone sprays or diffusers: Pheromones are natural chemicals that cats release to mark their territory and create a sense of comfort. You can use pheromone sprays or diffusers in your home to help your Siamese cat feel more secure and at ease.
6. Provide plenty of hiding places: Siamese cats may feel threatened by changes in their environment, so it’s important to provide plenty of hiding places where they can retreat to if they feel scared. This can be accomplished by placing boxes or blankets in secluded areas of your home.
7. Avoid sudden changes or loud noises: Siamese cats are easily intimidated by sudden changes or loud noises, so it’s important to avoid making sudden changes or creating loud noises that may scare your cat.
8. Keep their litter box clean: A dirty litter box can be a source of stress for your Siamese cat, so be sure to clean it regularly.

By following these tips, you can help your Siamese cat feel safe and secure in their new home. It may take some time for your cat to fully adjust to their new surroundings, but with patience and plenty of love and attention, they will eventually settle in and feel like a member of the family.
