I found a great tutorial for making a baby sling, so I made one for my cat out of an old flannel sheet. She loves to snuggle close to body heat in the cold weather, so this is pretty good, as it leaves my hands free.
I even managed to carry her around with me while I made a cup of tea. Problem is I'm not a young mommy anymore and it didn't take long for my back and shoulders to ache. Tuna loves it though!
Kudos to Leah Payne for posting the snuggly video tutorial (http://slingyourbaby.blogspot.com/2007/10/how-to-make-pouch-sling.html) on which I based my feline version.
