My kitten has cat flu - we have been told she will be ok but over the last 2 days her symptoms have got worse. She is very sniffly and sneezes a lot and has become very sleepy.

Poor Ginny! First, you can try starting her on an L-lysine supplement - this is an amino acid that has been shown to help the immune system fight off respiratory infections more effectively. Enisyl and Viralys are both good brands, and can be purchased over the counter without a prescription - just follow the dosing instructions on the label based on your cat's weight. If she's congested, you can also try using a humidifier or bringing her into the bathroom with the door closed while you take a hot shower - the steam and humidity help to break up congestion and temporarily relieve symptoms associated with respiratory infections. I'd also take her back into the vet.
