Hello everyone again!
Ragdoll is doing well, but I'm still concerned that she goes to the toilet frequently, and still does not completely empty her bladder by herself. I told the vets this and they think she's just going more often because she's extra sensitive, and to not be concerned as long as she is continent. However, I did a little research on the internet and found a condition called urethral sphincter hypertonus, which is described as this:
This happens when the muscles that relax to allow your cat to urinate don't relax. Your cat has to urinate, but they cannot relax the sphincter muscle that will allow them to go. In males, this can be a cause of urethral obstruction. In females, you may just see them going in and out of the litterbox frequently. There may not be any infection or inflammation present in the urine, but they can't fully empty their bladder when they are able to go, so they go much more frequently. This can also be caused by spinal nerve damage such as being hit by a car, or severe spondylosis of the spine, which is a type of arthritis of the spine.
The treatment for this consists of drugs to relax the urethral sphincter muscle, and in some cases, especially with spinal damage, drugs to increase the contractility of the bladder muscles. These are almost always lifetime treatments, if the urethral sphinter hypertonus is not temporary as a result of a UTI or urethral blockage.
All the symptoms sound exactly like her. I just wanted to ask if anyone has experienced this condition with their cats, and will she really need to be on drugs for the rest of her life if she does have this? And how much will the drugs cost? She is due to have her jaw examined again on February 18th, so I'm going to query this with the vets. Just very worried about how much it's all going to cost if they need to re-examine her and everything - I'm still paying off her other vet bills!
