Update - Found some small fleas on her bed 5-10 minutes ago and am now freaking out again! Partner is now respraying her bed and possibly the entire front room as that's where our cat has been the majority of the day. If they've fallen off in her bed, is it possible that this mean that they're dying? As the treatment we gave her two weeks ago states that over the next month, it should kill any fleas that feed on her within 24 hours and combined with the spray we used for the house (which I've no idea how long it takes to work once a flea comes into contact with it).
