Not familiar with that type of orchid but I have two catts that I bought with my bff in April (I had to ask her the date cause I'm bad at remembering that type of stuff), when I got them they weren't overly impressive but they looked good. I repotted them in plastic baskets and McGuyver'ed them into hanging baskets. Needless to say they looked like I took a needle to them and sucked every bit of moisture out of them for a long time. They needed frequent watering and I wasn't keeping up. The rainy season is here now so I'm now seeing vast improvements in the last month because of the increased wettings. Check the roots and trim what is dead, and do the usual cleaning of the cuts, repot and water the recommended amount and frequency depending on your environment, maybe it will get a kick start from that.
