You mentioned there has been another change in where he sleeps, this is disruptive as well and very well could be a part of the problem, but it's not insurmountable.
There are some very knowledgeable cat people on this site; keep working with your vet, see what other suggestions work on the behavioral aspect, give the kitty some time, and it'll all work out. We know it's stressful, but Clyde has been through enough - let him settle in. As I understand Russian Blues - they are very loyal once they realize you actually belong to them! Good luck, let us know how things go, and take care!
Clyde was on Hill's i/d for awhile but there is something in Science Diet/Hill's food that does not agree with him. He's been on Royal Canin Limited Ingredient Diet - Duck and Green Peas since November and he's doing a lot better. Sometimes i think the loose stools are from stress or if he gets into something he's not supposed to.
