Cat not using box.

Dr. Marie replied:

Oh, poor Millie. She's been through so much.

I am quite concerned if she hasn't urinated in two days. A lack of bowel movements are not as worriesome, but she really should have urinated by now. With that being said, I have seen cats that will go a couple of days without eliminating simply because of pain, discomfort or anxiety.

The fact that she is eating makes me feel that she is likely ok.

Did you witness the fight? Was it a fight with another cat or was it a dog? If it was a dog, then I would be concerned that perhaps she was shaken. When a cat is shaken there can be damage to internal organs. She could potentially have damage to her bladder. However, if this was the case she would likely not be eating anything at all. A shaking injury is unlikely to have happened if it was a cat fight.

Most likely she will urinate soon. My first inclination is to do nothing for now except what you have been doing - making sure that she has easy access to the litter box.

Another thing you may want to do is to take her cone off for a short period. This can be risky because we don't want her to scratch her stitches out. However, sometimes when a cat has a cone it seems to have a paralyzing effect on them and they don't want to move or use the litter box. It's probably not a bad idea to take the collar off and watch her closely. I would keep her confined to a small room so she doesn't take off where you can't see her. Perhaps, with the collar off she will feel comfortable enough to use the box.

If she has not urinated by the morning then I would have her seen. Or, if you feel that she is getting sicker (i.e. not eating, vomiting) then I would take her in to emergency today.

I really hope she improves soon!

Dr. Marie.
