Thank you for the additional information.
I am relieved that the skin is intact, as we can sometimes see 'degloving' injuries where the skin is stripped from the tail as well.
I suspect that Kacy has gotten his tail caught somewhere and this has lead to the hair being stripped from it. While it would be nice to know what caught his tail (predator, a tight spot, etc.), I am doubtful Kacy will reveal that information to us.
That said, his funny behavior and tucking the tail under him, are telling us that he is probably a bit stressed/on edge from this 'adventure' and the tail is uncomfortable. I suspect that this abrupt removal of hair was accompanied by some discomfort and pain. In this case, I would advise keeping him inside for the next week while to allow him to settle.
If there is no wounds, then we can breathe a sign of relief that there will be little infection risk (though it you do see any wee ulcers develop as this settles, then you can salt water bathe the areas to prevent infection). Pain-wise, I would advise monitoring him but if you do feel he is really sore or uncomfortable, then he will need to see his vet so they can dispense feline safe anti-inflammatories (ie. metacam)
Overall, I am very suspicious that Kacy has been very lucky and had a near miss today. This acute hair loss suggests an acute tail pull or the tail being caught. Luckily for Kacy, he is still moving it well (so neurological damage is unlikely) and he hasn't suffered any breech of the skin (either with degloving or wounds). So, I would advise monitoring him for discomfort (and have him see his vet if you are concerned) but otherwise the hair should regrow in time without any problem.
I hope this information is helpful.
Please let me know if you have any further questions.
If you have no further questions, I would be grateful if you would press the wee green accept.
Thank you,
Dr. B.
