Look for a lower, easier entrance or an open cushion that allows the cat to settle without crossing a substantial rim. Do not cut down the existing bed unless the manufacturer specifically provides an adjustment method, because altered seams or filling can create new problems. Observe whether the difficulty occurs only at that bed or also around stairs, litter trays and other familiar places. A new reluctance to step, jump or turn can deserve veterinary attention rather than being treated solely as a shopping preference. Keep a comfortable accessible resting option available while you assess the change. Compare the usable sleeping area and support as well as the entry height. A bed with a lower doorway can still have supportive sides elsewhere, so easier access does not necessarily mean giving up every feature the cat previously enjoyed.
Check the height from the floor to the entry lip, including any raised base. A low-looking rim on top of a tall frame may still require a substantial step before the cat reaches the cushion.
