“When a dubious pet psychiatrist loses his wife to his richest client, can a high school crush and obsessed cat owner rescue his practice and self-worth?”

Yes, agreed - ended up mistakenly omitting some words. Will be reposting with a new and improved line. Thanks for the comments guys!!

This logline suggests a very passive protagonist (after the inciting incident, it's up to two other characters - a high school crush and obsessed cat owner - to save the protagonist.) This concerns me, mostly because I'm not a good enough writer to be able to make that work, and I haven't often seen it done very well.

Also - in what way is the practice at stake from the protagonists' wife leaving? I can understand that he may go into a shame spiral after that, and so I believe that his sense of self worth hangs in the balance, but nothing seems to have happened to threaten his livelihood.

Sounds like a great hook here, but this logline gives no hint of the "fuel" of the film. I.e. what is the primary conflict that will drive the second act?
