I have a 5 year old rescue pig. He has access to outdoors but spends a lot of time just laying in his bed doing nothing. He almost seems depressed. I worry that during the day when we’re at work, he’s just sitting around doing nothing. We had a cat who passed away, so now it’s just him and I’m worried he’s lonely and not getting any enrichment.
What are things a pig can do during the day? How do we keep him engaged and entertained while we’re at home as well? Any ideas appreciated!
