I am sorry I didn't see this earlier.
I am so glad the fluids worked their magic with Tama! He just has the same weight now as Orion- they seem to be similar not only in color.
You know that Filou survived kidney failure for 5 years. He got weekly fluids and was happy, eating well and having all the fun an Aby is meant to have. I hope Tama will be just the same. How old is he, BTW?
I am wondering whether Abys are prone to kidney diseases.
