Welcome to the Forum, @jjl61886! 
Which Wyze Cam model do you have? Is it the older Cam v2, Cam Outdoor v2, Cam Pan v2, or something else? We should probably try to get your topic moved to the Cameras category and get a different tag on it to improve its visibility.
If you’re using a regular Cam v2, then the last time I asked the chatbot on the Support site, it gave me this answer:
(See MicroSd card size chart for all Wyze Cams - #5 by Crease for context.)
For most Wyze Cams, I believe you should be able to use a microSD card set for Continuous recording and play back your own locally-recorded videos without needing Cam Plus or any other subscription. If you have your camera trained on something like an indoor food dish that should see motion only when your cat visits (or possibly when the feeder dispenses food), then you might even be able to just set microSD recording for Events Only to squeeze more use out of a smaller card and make your recordings easier to find. (Note that I don’t have any Cam v2s, so I’m guessing about the settings based on what I see with other Wyze Cams.)
