Fattening others

My piglet has high blood pressure and a love for fruit-based desserts, any ideas/recipes to maximize his intake?

If you're concerned about his blood pressure, I'd recommend trying to get him to eat healthier foods just in higher quantities. For the most part the source of the calories doesn't matter just as long as he's eating more calories than he burns everything past that will be stored as fat. Hopefully that'll minimize any health risks he might have

Get that blood pressure stable first. Even if he is eating low sodium foods, that still adds up.

Once his blood pressure is stable, then you can reassess.
