So sorry to hear about Bastian! Bless his little kitty heart. Crystals can be so painful for them. Is he on medication now? Be sure to ask the vet when you go to pick him up if he should be put on the special diet for urinary tract. Our Scooter had a repeating problem with this coupled with UTI, and he's on a special Science Diet for urinary tract. He has to remain on it for the rest of his life, but it should help keep crystal re-formation from happening...hopefully!! Lots of headbumpies to Bastian, I hope he's feeling better soon!

**hugs**
