Multiple cats can share a single cat tower tree house, but it's essential to select a tree house that can accommodate their size and activity level. Look for larger and more robust structures with multiple platforms, perches, and hideaways to provide enough space for multiple cats to use simultaneously.
However, keep in mind that some cats may be territorial or prefer their space. It's important to observe your cats' interactions to ensure they are comfortable sharing the tree house. If conflicts or stress arise, consider providing additional cat towers or structures in different areas of your home to allow each cat to have their space.
Regularly clean and maintain the tree house to prevent the buildup of odors and to keep it appealing to all your feline companions. With the right tree house and monitoring, multiple cats can enjoy the benefits of a shared space for play, relaxation, and scratching.
