What Does Given Sq Lh Distal To The Stifle For A Kitten?

I have a 4 yr old Siamese that has an inguinal hernia and we are planning on having him neutered. I would like to know the age of my kitten is he will be spayed or do you think it’s best not to? He’s been acting very lethargic, unresponsive and rolling around in his sleep. Can this behavior be normal for an older cat? He was born October 26th 2007 so he won’t be 5 yet until April 16th 2008. His weight doesn’t seem abnormal as well at 10lbs but there is a difference between 10lbs and 15lbs.. There isn’t much swelling on either side of his abdomen which worries me some because if no one ever told me about hepatic lipidosis I would never had thought twice about it…
