As Ivy said best way to find out is switch to a more dominant. One of my starters returned Swanky Lite with a Swanky lite puller first breed, I switched immediately to a more dominant whisker in the hopes of hiding it in a girl for a backbreed, so far he has declined to pass his whisker shape again but I will persevere, even if I get a boy I'll just pick a cat with a whisker recessive to the oneI'm using to hide and carry on trying to get a girl hider. Unfortunately its unlikely to be a fast process but if you do have something new its instant placement. This is why new recessives don't tend to be found until a little while after a release, backbreeding takes time and patience and a whole heap of luck in getting the right hiders to backbreed in the first place, then relying on 2 cats to pass hid instead of one. Good Luck if you do decide its worth digging to see.

Tiger! - Shaow is dominant to Toyger - Snow
Nice clear proof showing the Toyger - Snow pulled by the more recessive Chateau Cat - Toffee Caramel
Just had this baby today.
I've started running some tests on my two Tiger!-Shadow starters and one of my shadows.
Kitten is unpacked and will be tested for his hidden fur.
Enyeto is now paired with a Russian White mate - will see how he gets on with her (Going high on the dominance chart).
The Jelly Nelly starter is paired with a Balinese - Flame Lynx mate and the Kaleidoscope girl with an Australian Mist - Snow. First kittens due in 5 or 6 days time.
Tiger! - Shadow probably dominant to Aussie - Snow. Kitten unpacked for testing.
(profiler has made a mess of the dates - but it is Archibald's line)
Tiger! - Shadow is recessive to Russian - Black.
Unpacking to pull the hidden fur
Tiger! - Shadow is dominant to Australian Mist - Snow
Tiger! - Shadow is dominant to Balinese - Flame Lynx.
Tiger! - Shadow is recessive to Maine Coon - Silver Tortoiseshell
Unpacking to check hid, he threw hid last week so fingers crossed he didn't this week
