I have a cat that is 10 yrs old and have noticed lately that she ( spunkers ) is drinking a lot of water. I have been feeding her dry food and now considering wet food ..... is this ok to gradually make the change? She likes wet food.

Wet food is actually biologically a better food for cats. Dry food is easier for humans, but cats are desert animals and tend to run a little dehydrated if fed only a dry food diet. Since Spunkers already likes wet food, you should be able to easily transition her over to a wet food diet. However, since you have noticed that Spunkers is drinking more water than normal, I would recommend having her evaluated by your veterinarian and run some routine bloodwork and a urinalysis to make sure there aren't any metabolic changes that are causing the change in her water intake. A canned food diet is always a good idea for cats, but we also need to make sure there isn't anything else going on that needs to be treated. I hope that was helpful.
