I have noticed that my seven year old cat is lately drinking a fair amount of water, even out of my glass, when she never used to drink any? She has dry food mixed with Felix pouches. Thanks all.
One of ours drinks water out of anything given the chance but this could be the start of diabetes or kidney problems, as previously mentioned. I am assuming your cat has access to a bowl of water all the time?
You need to take the cat to see the vet, for a blood sample to be taken to test for diabetes and/or kidney disease, both of which are common in cats of middle to older years.
If the cat does have either of these two conditions, they can be treated, but the longer they go untreated, the more harm will be done to the cat's health.
If this were my cat, I would have her at the vet's first thing in the morning.
