I have always done my sub-Q's myself, as there's no one here to help me. It helps that Cleo is a very mellow and laid-back kind of cat. It was more difficult when I had to do sub-Q's on my parent's cat, Samson. He was evil incarnate. I wore leather gloves and long sleeve shirts when I did his....even during the hottest days of summer! Did you get a chance to view the link about sub-Q's? I'll post it again, just in case you didn't...http://www.weirdstuffwemake.com/weir.../catjuice.html
Here's me, giving Cleo her fluids by myself. She actually loves getting her fluids. I warm them, and she purrs and kneads through out the process.
I always make sure to give her a treat (usually shredded boiled chicken breast) when we're done.
