Hello cosplayers

For Halloween at work we get to dress up (for a whole week of it, woopwoop) and after making my mind up about umpteen times over, I've finally settled on the cheshire cat.
Only to mix it up a little I was going to attempt the new movie version (Which looks like this).

I already have an idea for what I'm going to do for the main body of the costume, but I was hoping to have fur arm-warmers and tail (and possibly ears)
Only... well I think you can see my dilemma.

What's my best course of action? Hunting round for appropriately grey-and-turqoise fur? Buying two separate colours and sewing them together in stripes?
How easy is it to use fabric dye on fur? I was considering attempting to paint on the dye with a mascara brush or something similar, perhaps using a more liquidy ink based dye to avoid the fur losing all its fluff, has anybody tried anything like this before? How did it go?
Is there anything else you can suggest, bearing in mind I am low in budget and only have 'till the last week of October?

Thanks in advance, Shini.

two different furs. don't even try to dye stripes onto fur.

I think the best way of doing it would be buying grey and turqoise fur and sewing it together. that way the stripes will be more acurate!

There are ways to dye furs, but it is usually rather difficult. Sew in strips of each colour for the best results.

Well that's a pretty unanimous consensus!
Thanks guys
