N' Manoch krub i wonder which one did you get the Savu python or the Macklot's python krub? I never seen real Savu python in the market for a long time. Most sold as Savu python in the market is Macklot's python. The easiest differance between these two is the Savu's eyes are whitish but this isn't found in Macklot. If you really got the Savu one, you are quite lucky na krub. The Savu will colour in reddish brown to brick red and more beautiful than Macklot.
I never experience feeding problem with Savu. I guess that this Savu might be bought from P'Tui shop cause his shop always supply the Indo-Australian snake. It can take up to 2-3 weeks for snake to familiar with the new environment just give yours the right condition ie hinding place, water supply and do not handle it during the adjustment period. There is nothing to worry as long as your snake is healthy.
After your snake settle down, try to deparasite it since WC animals are always heavily parasited and from time to time resulting to death occure.
