Strange Behaviour with Tail

[Rebecca.G]

I have been through a lot with my 8 year old female cat. Been in and out of the vet and spent thousands trying to find solutions. Long story short, my main concern now is her weird behaviour with her tail. She’ll stare at it, run away from it, and recently has started aggressively growling, hissing, snorting, and clawing at it. She also runs around frantically while she’s pooping as if she’s in pain. The only modicum of information I’ve gotten is that there was slight thickening of her small intestine in an ultrasound, but she does not have diarrhea so my vet is hesitant to think it’s IBD.
they’ve told me they think it’s just anxiety but I refuse to believe that.
Has anyone seen this or experienced this before or have any idea what could be causing it??

Hi. Anxiety, which it does sound like that could be what is going on, would need to be addressed by reducing her stress level and perhaps trying various calming/anti-anxiety products - both OTC and/or prescription. There is a condition called feline hyperesthesia which is often thought to be tied to anxiety - again, calming and de-stressing are generally the primary attempts to help with this condition. Inside this article on this condition are some others related to stress, maybe taking a look at these can help you decide how to proceed.

I’ve heard of it. It’s the response everyone gives when I describe what’s happening.

I think something is causing her pain but will probably have to settle with never getting a proper answer

Has the vet recommended any other testing? Possibly put her on pain meds as a trial to see if anything changes? It is not a permanent solution, but if a pain med would help, at least you have a direction to head in.

Maybe it is nerve-related? That might require more $$$ by seeing a neurologist. If not, then an internal med specialist that might recommend some other forms of testing. A lot of the specialty groups have a neurologist on staff, and many times there is a collaborative effort among staff members.
