So what variations on colour are acceptable?

Cool or Warm they're still adorable
Toygers when born are normally ‘cool’ coloured, that is to say they are somewhat grey / pumpkin coloured with dark stripes, and it is not until they are a few weeks old, that you try and guess what their final colour might be. Unlike other breeds where there are a number of accepted colours we describe all of our Toygers as ‘Brown’ Toygers.
Although as with every rule there is an exception, the exception in the case of Toygers, is what we call ‘Blue’ Toygers. Although the Blue are not recognised in the breed standard, very occasionally a liitle ‘Blue’ Toyger is born. These make stunning pets, and normally have great markings, but cannot be shown although they may be of full Toyger x Toyger breeding (SBT).
