The wheaten Burmese, aka the Burmese agouti, is unique as it is the only pointed rat that is also ticked – and while that may sound like even more to get right in one rat, they’re a more forgiving variety to breed than the standard Burmese.
Wheatens vary in shade as much as normal Burmese do – from the correct cool sand colour to a particularly odd, almost cinnamon shade. In a fortunate accident, the correct paler colour is bred using the warm, to-standard Burmese, meaning you can run Burmese and wheatens together and produce offspring of the correct colour for both varieties. In the US, it is the shade resembling cinnamon that has been standardised over the sand colour, but they have kept the name of Burmese agouti rather than wheaten Burmese.
Probably the most difficult part of the wheaten to get right apart from the overall shade are the feet. The feet of any agouti-based rat tend to be paler than the overall top coat (yes, even when the standard insists they’re to be the same). Wheatens are supposed to have dark points on their feet, and this can be fustratingly difficult to get right.
Genetics: agouti with one copy of the Burmese gene, and two copies of the Himalayan gene (A-BebuBebuchch). As with Burmese, wheatens can be produced either based on Himalayan or albino (chc or cc). The Himalayan version looks like a wheaten with paler and less distinct points. The albino based version will have no points.
