awwwwww, 'head bumps' ! How cute! I love head bumps from my cats!
My other cat, Fluffy meowington something or another (I forgot the long ass name my daughter gave this cat)
The only way I can pet her is if I hold my hand a couple feet off the ground, then she kinda loops up and pets herself on my hand........kinda like a fish jumping out of water. She's so cute.
