Hello Rose. Both of my cats were diagnosed with the cat-flu when they (and I) were living in the UK about 4 years ago. They are both still fine and apart from some snuffles every now-and-then they are happy and kitten-like at the age of 8...so just remember, they can be just like us with our winter colds and flus - annoying but not too serious. But, as Pieper's Mom says, when(if) you get the chance you should take them to a vet.

Troy.
