I've had the girls 2 weeks, which probably explains why I'm panicking so much now! Should I be worried? River and Melody are both about 12 weeks old, and are normally hyper kittens- charging around the room chasing each other, playing with everything, climbing the curtains and eating everything in sight! Today however they have been very quiet and asleep on the sofa all day. They haven't eaten much- their was wet and dry food left in the bowls during the day, and only River ate a small amount of the two types of wet food I put down this evening, Melody just walked off. River is showing a bit of an interest in toys, but again Melody doesn't care. I can also hear Melody's breathing when she's sat next to me, so I'm starting to worry a bit now! What could it be? What should I do?
