You know you have a happy and contented cat

when you rub its belly and he enjoys it so much, his little wee-wee pops out in appreciation.

You know it's Monday when...

You are mixing up a jug of iced-tea, and you realize you need more iced-tea crystals for the amount of water you are using (not strong enough). So you grab what you think is the iced-tea container, only to discover upon opening it that instead you have grabbed the container of dry cat food.

Luckily, you noticed before you actually added anything but still.
