Kyzoor,
I don't want to get involved in this thread, but I would simply ask this:
Please do
not sell the cat tree and cages that you've listed in the Products section.
If your cats have (or had) feline panleukopaenia (FPV), the virus could be transmitted to another cat via the tree or the cages. I worry especially about the cat tree, as it would be nearly impossible to disinfect it completely. RM300 is a very attractive price for that cat tree, and I worry that someone may be very eager to buy it without realising the risk.
I wish your remaining cats the best of luck and good health...
