We've been sick at my house this week. A nasty spring flu/cold hit both Mike and I.
While we were laying around (moaning) we realized that we have five little therapists in the house. That's right... Our cats! 
All five of them, in their own unique ways, help us to feel better when we're sick or down in the dumps. When either of us is sick and bundled up on the couch, we can count on Ben and/or Miss Girl curling up with us. I swear you can feel their kitty energy transferring to us! Miss Girl especially seems to be aware that we're not feeling good. She glues herself to us! She is this tiny little cat with problems of her own, but she wants her pet parents to feel better and tries her hardest to help!
Ben is a lover anyway, but when we're sick he really kicks it up a notch. He isn't a purr-er. But he is learning to purr. We call it purrgling. He gets a good loud purr off, and then it chokes him and he sort of gurgles. It's very cute, and endearing! You can tell he's really "therapizing" (my own made-up word) you when he gets to purrgling!
Oscar, Henry, and Luna all try to help. Luna is the least helpful, partially because she is so big! (17-18 pounds of black cat energy!) She wants to curl up on you, but it kind of winds up hurting rather than helping! Oscar is my boy - he likes to curl up around my head. Which is nice, but sometimes, not exactly what you want when you have a cold!
Do you have animals that help when you're sick or feeling blue? Even when they are just doing something crazy to make you laugh, they help!
