You can't get away with it... I remember your gorgeous guineas too

I think the whole forum was in suspense & waiting with bated breath when the beautiful bug eyed Fudge went in for an op (spay I think).
The forum went very quiet until you posted a few days later, she'd come through successfully.

My new girl Tiggy has a similar face to Crunchie but hair like Mallows...
She's had a few bum baths as her botty hair was rather wet & widdly!
So I opted for a botty trim & now she's sporting a nice clean bum that smells as fresh as a daisy

She has reasonably long hair all round & just a trimmed botty
Guinea safe shampoo will clean them nicely, then trim out the excess long/stained hair & if there's no hair to be stained it's easier... I've always used Johnsons baby shampoo as I rarely bathe any of mine. But a lot of members use 'gorgeous Guineas' range of shampoos etc with good results.
Oh & a little snippet of info... Girls wee towards their back end & boys wee towards their front end... Might help decide on the most effective trimming areas xx
