Unfortunately he’s now on and off doing a weird wheezy breathing. I’m going to take him to the vets just to be sure. The last week he’s suddenly become more tame and let’s me pick him up and he’s also got an eye droop (which he’s had for a couple months). It’s all a bit weird so I’m going to pop to the vets just to be sure.I’m sorry I don’t have a clue. Has he done it again since you did the video? Perhaps email the vets and see what they think if you’re still worried.
