No, its only 4 am!

I am so tired. I have a disabled Cat that likes to wake me up at 4 am, he's been really good lately and has not been jumping on my head until about 6 am and this i can cope with, but 4 am is a little too early. The thing is that i can not seem to go back to sleep, if i try he likes to get onto the bed and jump on my head until i get up, little monkey! But what can you do, he needs the toilet and his breakfast and so i have to get up... Normally i like this time in the morning, to be alone with the Dawn is a pleasure, but what with the Carers course, im mentally tired and so need a little bit more sleep.. Lets hope that he is just going through a stage and eventually settles down again until 6am..
