Yes, a cat housing kennel can be used for more than one cat, but there are some important factors to consider when housing multiple cats in one kennel.

1. Size of the kennel: The size of the kennel should be large enough to comfortably accommodate all the cats. A good rule of thumb is to have one square foot of floor space per cat. This will allow the cats to move around freely and avoid overcrowding, which can cause stress and behavioral problems.
2. Compatibility of the cats: It’s important to consider the compatibility of the cats before housing them together. Cats that are not compatible may fight, which can lead to injuries and stress. Introducing cats slowly and gradually can help prevent conflicts.
3. Separation options: If the cats are not compatible or if they need to be separated for any reason, it’s important to have separate areas in the kennel where they can be isolated. This will prevent any fighting or stress.
4. Resources: It’s important to provide enough resources for all the cats in the kennel, including food and water bowls, litter boxes, and bedding. Having enough resources will prevent competition and stress.
5. Environmental enrichment: Multiple cats in a kennel may become bored or stressed without environmental enrichment. Providing toys, scratching posts, and climbing structures can help keep the cats entertained and happy.
6. Hygiene: With multiple cats in a kennel, hygiene is particularly important to prevent the spread of disease. The litter box should be cleaned daily, and the kennel should be cleaned and disinfected regularly.

Overall, a cat housing kennel can be used for more than one cat, but careful consideration and planning are necessary to ensure that the cats are comfortable, safe, and happy. By providing enough space, resources, and environmental enrichment, and by maintaining good hygiene, multiple cats can be housed in a kennel successfully.
