Hi there and thanks for your question.
Cat urine doesn't always have a smell to it. If your cat has been drinking a lot of water the urine can be dilute and therefore will not be as stinky.
If your cat continues to urinate in strange places then you may want to have her urine checked by your veterinarian for the presence of infection, kidney disease, diabetes, etc. If your vet does not find a problem then they may suggest behavioural modifying medication such as amitriptylline.
I hope this information helps! If you have more questions regarding this problem, just hit reply. If I am online I will respond right away. Otherwise I will respond as soon as I come online again. Or, if my answer is sufficient, then please hit accept. Thanks!
