I have a tissue lover too.
My Sidney, now six, loved tissues when he was a kitten. I thought it was cute and indulged his habit. He would sit up on his hind legs and hold the tissue with his front paws and shred and shred and shred. (and occasionally get the tissue stuck to his tongue)
Of course, it did leave quite a mess to clean up - but as you will soon discover on Pet Talk - most of us love to spoil and indulge our pets:D
If you don't hide the tissues, then probably the only thing I would recommend is to make sure that you're using tissues that don't have lotions or other scents or chemicals in them.
Also, you could try to keep the tissues in a box so that your kitty would just do her shredding there - it would be much easier to clean up.
Oh, Sid did eventually outgrow this obsession - but I can still give him the occasional paper tissue or napkin or paper towel and he will still shred it.
Welcome to Pet Talk and enjoy your kitten - they grow up way too fast
