This is a cute way to pop the difficult and nerve jangling question, “will you marry me?”…..
I had never thought of this. It would have made things easier for me, I think and it encourages men to like cats more (maybe). Your girlfriend comes around to your place and she loves your cat anyway.
You say nothing and she goes to stroke your cat. The question has been popped 😉 . But in a very gentle way and the question is indelibly linked to your cat so if the answer is yes, it should benefit your cat as she carried the message.
There are some potential pitfalls though. What if your cat was spooked for some reason and as the love of your life went to stroke her she smacked her hand with her paw and scratched her slightly?
The “pop” might turn to “crackle” and then shatter.
