I have a long hair cat and usually his tail is real full and fluffy but, lately it looks thinner and raggety. Could something be wrong or could it be because of summer shedding?
It could be any number of things, all of which are pretty insignificant. Uneven shedding, excessive grooming of her tail, rubbing it against something repeatedly, fleas if you think that is at all possible....... I would just keep an eye on it and try to check for fleas and check the skin on the tail if you can part the hair and see it. Make sure it isn't red or irritated or lumpy/bumpy. Otherwise, give it some time and see what happens.
