Gotten worse?

So I'm not too thrilled about this. Tonight I had the impression that Lada's neck has gotten worse again. It is really hard to tell, but it seemed to me like his neck fur is thinner again.

Tonight's picture:

Of course he is leaning forwards in this photo, so it's more obvious then. But even with that taken into consideration…

I will not be terribly surprised if there's another trip to the vet in the not-too-distant future.
