Losing tail fur

[Toruga]

Hi, I have an almost year old female grey that is special needs and she had been slowly losing her tail fur over the last three months. What was once nice and bushy is getting pretty sparse. Want sure if this is vitamin related or something else. She gets a pretty well balanced diet daily including pet block. Any ideas what going on?

its the moult A normal occurence which can be more or less drastic depending on the individual. i have a white neuro, 7 yrs old, wo end up looking like a white rat every year for a couple of months. Some of my other NRs get a thinner tail for awhile and one guy scarcely seems to lose his ... all are on the same diet, same lifestyle.
