G'day all. My cat Mikka will be coming to Boston in Jan.

I'm sure she'll love the -10 F weather here. But I'm excited! Anyway I'm planning for her arrival. I have a question about cat litter - she's used to using this brand called "Fresh n Easy" which is a granulated (crystal) litter made by a German company called Trixie. Unfortunately this cat litter is not available in the US - the closest I found was one called Pet Gold Crystals Premium Cat Litter at Petco. Is it going to be a really big deal if I have to use this litter? It's the same kind (crystal non-clumping). Or will she get confused? Note that she'll be traumatised after a long flight as well.
