    You can use a lookbehind assertion, (?<=...) to assert that something needs to be present for the regex to match (here, cats+), without making it part of the actual match result.

    For example:

    const example = 'a cat gifi picture';

const regex = /(?<=cats+)(w+)/;
console.log(example.match(regex));

    will log ["gifi", "gifi"] (the entire regex match is gifi and the only capture group is gifi).

    (?<=cat[ ]+)(w)+

    add new lines, tabs etc to or condition in bracket if need be. I think this should work though.
