Cat housing kennels can be used for multiple cats, but there are several factors to consider before doing so.

1. Size: The size of the kennel is an essential factor when it comes to accommodating multiple cats. The kennel should be large enough to allow each cat to move around freely, stretch, and jump without feeling cramped.
2. Temperament: It is also important to consider the temperament of your cats. If your cats get along well and are used to sharing a space, they may be able to share a kennel without any issues. However, if your cats are territorial or have a history of fighting, it may be best to keep them in separate kennels.
3. Compatibility: In addition to temperament, the cats’ compatibility should also be considered. Some cats may prefer to have their own space and may become stressed or agitated when forced to share a kennel. It is best to monitor their behavior and interactions when introducing them to a shared space.
4. Hygiene: Sharing a kennel can increase the risk of spreading diseases and parasites between cats. It is important to clean and disinfect the kennel regularly to prevent the spread of germs and maintain a clean environment.
5. Resources: Multiple cats sharing a kennel should also have access to food, water, and litter boxes. The resources should be placed in separate areas to prevent competition and territorial behavior.
6. Supervision: It is important to supervise cats when they are sharing a kennel, especially during the initial introduction. This can help prevent fights or aggressive behavior and allow you to monitor their interactions.

In summary, cat housing kennels can be used for multiple cats, but it is important to consider the size of the kennel, the temperament and compatibility of the cats, hygiene, resources, and supervision. Proper planning and monitoring can help ensure that your cats have a safe and comfortable shared space.
