Yes, in some cases, a cat housing kennel can be used for other small pets, depending on the size and needs of the animal. Here are some examples of other small pets that may be able to use a cat housing kennel:

1. Rabbits: Rabbits are similar in size to some cats and may be able to use a cat housing kennel. However, it is important to make sure that the kennel is large enough to accommodate a rabbit’s needs and that it is well-ventilated to prevent overheating.
2. Guinea pigs: Guinea pigs are also similar in size to some cats and may be able to use a cat housing kennel. However, they require ample space to move around and may need additional accessories like hay racks or tunnels to keep them entertained.
3. Ferrets: Ferrets are slightly smaller than most cats and may be able to use a cat housing kennel. However, they are active animals that require plenty of space to run and play, so a larger kennel or playpen may be necessary.
4. Small dogs: Some small breeds of dogs, like Chihuahuas or Yorkies, may be able to use a cat housing kennel as a temporary sleeping or resting area. However, they will likely require additional space and accessories for exercise and play.

It is important to note that not all cat housing kennels are suitable for other small pets. Before using a cat housing kennel for another type of animal, it is important to research their specific needs and make sure that the kennel provides enough space, ventilation, and other necessary features. It is also a good idea to consult with a veterinarian or other animal care professional to ensure that the kennel is appropriate for the specific animal you are caring for.
