I also try to get him to drink more, I take a glass of water to where he lays, and then he'll often drink while I hold it.

Please send some good thoughts to Fister tomorrow.
Wet food: when you remove from fridge, put the amount you are giving him in a dish / bowl and microwave it 15 to 20 seconds. May need to add a drop or 2 of water before hand, give it a try each way. Cats don't normally like cold food. Stir it around too.

Drink: if he needs to drink more, add some chicken broth or tuna water to the water bowl.

tests: I usually get the Senior CBC, covers everything. Pricey, so be prepared or ask first.
Prayers for Mister Fister!
