Cathouses are establishments that provide temporary housing for cats. If you need to find synonyms for this word, "cat shelters" or "cat sanctuaries" are good alternatives. Alternatively, the words "cat rescue" or "cat adoption center" describe organizations that help cats find new homes. Another option is to use the term "feline shelter" or "feline sanctuary" which denotes a refuge for all cats, not just those in need of a temporary home. Regardless of the term used, these places provide a safe haven for cats and help to ensure that they are taken care of.
