Ambika definitely sounds as if her legs are bothering her more than when I was there six weeks ago. Her arthritis seems to have worsened so quickly compared to 20+ years for Shanthi. My heart breaks for Shanthi; I've never seen visible abscesses on her feet before..... You used the plural--both feet had abscesses?
I spoke with several keepers while there and they all said that Ambika's arthritis is fairly new only developing quite quickly over the last two years. As with Shanti it was unfortunately both her front feet that had abscesses. You can tell she is in a great deal of discomfort when moving around even though she seems to be moving around much more than the last few visits. I would like to think that the drive to be where ever Bozie goes is what motivates her to move around at times. The two are always not far from each other whenever I see them and whenever Bozie moves if theres no food in front of Shanti she seems to follow her.
I will post some pictures when I get a chance to. They are all on my phone so i have to upload them to my computer before posting.
