Your quilt is far from dull and certainly does not warrant being a cat hair catcher.
It's actually quite spectacular and your choice of the pink/burgundy borders on the blocks make them all stand out to make a stunning quilt.
The two suggestions of taking an inch or two slice off to vary the pattern is a good one. Also, twist the blocks around for different points to the centre. With it being square if you have matched sets, that way you can actually make four different kaleido blocks! :)
