My female cat is having some trouble urinating. She is going a small to medium amount but 15 minutes to a half hour later she is going in the box and sitting there with no results. She is nine years old and a bit heavy. She does go to sleep for hours without going to the box. It's just like she feels like sometimes she still has to go. She is not crying, there is no blood and she is eating normally. I am making soup out of her food by adding water and she is drinking that, but I haven't really seen her drinking her water. There is a fountain, but she won't use that.
I have been through this before with two of our male cats but never with a female...
I know she has to go to the vet, but I am a bit short til next week. As she is urinating, although perhaps a smaller amount then normal how pressing is this issue and is it very common for a female cat to get it?
