Can you get your kitten registered if he was a stray?

It depends on the specific organization or registry you are looking to register your cat with. Some organizations, such as the Cat Fanciers' Association (CFA), allow you to register stray or rescue cats as long as they meet certain criteria. For example, the CFA requires stray or rescue cats to have a "distinctive phenotype" that is not common to any breed, and they must be at least 8 weeks old. Other organizations, such as The International Cat Association (TICA), do not allow you to register stray or rescue cats.

If you are interested in registering your stray kitten with a particular organization, you should contact them directly to inquire about their requirements and procedures.
