If it's taking hours you may have run into a bug with the current version that causes issues. If you visited Snake while a Consensual Predator is prey to Snake and you don't know them, it kind of breaks the game unfortunately. This should be fixed next version (need to do testing).
If you've done this or aren't sure, you may need to start a new game, or wait for the next update to use that save file.
Start a new game, then keep an eye on Predator Info at the bottom. Wait for Neko girl to be prey to a predator, then find that predator. Can enable Debug buttons in the options menu if you already did content and want to speed it up. Be careful with 'Max All Relations' if you do though, as it might cause some Neko girl content to get skipped.
