Periodically, I will see wet spots on my bed about the size of a quarter from where my cat was sitting. However, I woke up today and there was a wet spot about the diameter of a softball. At first, I thought it was urine because she often goes on my bed but she had been doing really well lately. I got down to smell it and it had no smell and she didn't look like she knew she had done something wrong. I am not sure where the liquid came from, it's clear and odorless. She is very healthy and happy as far as I can tell. She also eats and drinks often with no problem. Any suggesstions or thoughts? She is my BEST friend and my heart I don't want anything to be wrong with her.
