I agree on the fertilizer. Plants ready for repotting will often have a fair percentage of dead roots in the pot. I think you will find with experience, that roots have shorter life spans than leaves. I generally start cutting off dead roots from the oldest end of the plant, and stop when I find I am cutting into a live root. Need to see a picture for the leaf yellowing. The shriveling is probably just a response to moving from a humid greenhouse to a dry house. Not really a sign of trouble, just adjustment. However, since you repotted, this shriveling could get worse for a while. You might want to throw a clear plastic bag over the plant for a couple of months until it can grow new roots, tho when it will grow new roots is not clear, as they are sometimes very seasonal, so play it by ear, and be sure to leave plenty of opening around the bottom of the bag, as you must have air exchange to help the potting mix dry out. For sure you want a wet/dry cycle for your Catt at the roots.
