I'd plan a vet visif for him.
While it might be something he will get over, cats are not as hardy as one might think in some ways and he may need vet care to get back to 100%.

If he is going to be in the office alone for the weekend I'd suggest vet care for that reason too.
If your cat might have gotten into anything toxic, appears dehydrated (see if a pinch of skin over the shoulder blade stays stuck in a tent form or flows back down normally when released), has a rectal temp over 103.5F (normal is 100.5-102.5 Fahrenheit or 38 - 39.2 Celsius ), has gums or tongue that look white, blue, gray or yellow tinted where they are normally pink, has a slow color refill if you press on a pink area of gum or tongue, or is becoming over time more lethargic and non responsive to you then you may want to get the cat in to see a vet as soon as possible.
This might be a viral infection, it may be a bug bite, he may be ill from biting an electrical cord or swallowing a non food item. Even an indoor cat can get into trouble.
Hope this helps you!

Thanks Nancy.....Cooper's home is a real estate office so we'll be here over the weekend and will keep any eye on him. So, his gums are pink and he's napping back out in the open.....so we'll keep an eye on him......
Many thanks!

Linda
