It's a happy feeling to have your cat feel safe and trust you enough to sleep so relaxed that way even though summer heat it's not so fun . Good news is winter is coming soon
Sammy has ALWAYS loved to snuggle/sleep where I am/with me! I take it as a compliment! Not sure what I would so without him with me at night to be honest with you!!
I think Suki is going to HATE winter! We keep the house at 65. She is currently laying on a furry bath rug with a heating pad turned on under it. The house is about 70 degrees now.
