Recently (the last few days) I've noticed that whenever my boy's straining (like when trying to chew open a toilet roll tube to get to his food) his eyes bulge a lot. When he's doing anything else his eyes are completely fine, no bulging, no discharge/redness, and he can blink like normal. However when I give him his food in a toilet roll tube his eyes look like they're about to fall out, but they go back to normal whenever he stops. You can see it in this (

I just want to know if he's OK, and if it's safe for me to give him his food in toilet paper rolls still as I don't want him to damage his eyes.
Bulging eyes when straining?
