It's the first time this week marmaduke has been awake before I go to bed. When he woke I scooped him up and noticed his testicles were relaxed, but they were hanging really low. When he had been awake around 5 mins his testicles had retracted again but there was still a noticeable bulge.
His testicles looked completely normal it's just the bulge. I took a photo but it's not great. He is still eating and drinking plenty and I haven't noticed any change in toileting.
