I am so sorry to hear of your loss and what a terrible way too. I have been to many petshops to look at their boarding facility but i just dont have the heart to leave my babies with them, not even for 1 day! Most of them cage the cats like chicken. It's dirty and smelly. The worst place i have seen is in Pandan area (KL) where they put cats in wire cages. The f/male attendant sprayed water on floor without consideration. I actually saw the poor cats shivering and most got wet.
I hope all forumers can share their experience or tell what they have seen so that it's a warning for everyone.
