If you’re a rabbit or guinea pig pet parent, you’ve probably asked questions like: “What should I feed my rabbit?” or “Is it OK to feed vegetables to my rabbit?” It can be hard to find clear, consistent guidance, especially when different sources say different things.

That’s why we created the Selective Nutrition Guide App: a web-based app designed to help you build a simple daily routine, understand fresh foods, and feel confident about feeding your pets, step by step.

What is the Selective Nutrition Guide?

The Selective Nutrition Guide is an easy-to-use online tool for:

  • Rabbit pet parents
  • Guinea pig pet parents
  • Veterinary professionals
  • Rescue Centres
  • Pet Retailers

It brings together practical feeding support in one place, including:

  • Feeding Calculator
  • Body Condition guidance
  • Choose Food guidance
  • Fresh Foods guide
  • Weekly Meal Planner
  • Saved Plans for each pet
  • Dedicated rabbit and guinea pig sections (so guidance stays species-specific)

The app was developed with the help of Supreme’s specialist Veterinary Advisor, Molly Varga from The Exotics Animal Vets, to keep recommendations clear, helpful, and grounded in pet-care expertise.

“What should I feed my rabbit?” Start with a simple daily routine

Feeding well doesn’t have to feel complicated. The Selective Nutrition Guide App helps you create a plan you can actually stick to, so you’re not second-guessing every day.

Using the app, you can:

Keep routines consistent with a Weekly Meal Planner and Saved Plans

“What should I feed my guinea pig?” Guidance tailored to guinea pigs

Guinea pigs have their own nutritional needs, which is why the app includes guinea pig-specific sections (including feeding guidance, body condition, and fresh foods).

Fresh Foods guide: “Is it OK to feed vegetables to my rabbit?”

Fresh foods are among the most common sources of uncertainty. Many pet parents want to offer fresh vegetables and occasional fruit but aren’t sure what’s suitable or how to include them in a balanced diet.

The Fresh Foods section helps you explore everyday fruits and vegetables so you can answer questions like:

  • Can rabbits eat vegetables?
  • What vegetables can rabbits eat?
  • Can guinea pigs eat vegetables?
  • What fruit can rabbits eat?
  • What fruit can guinea pigs eat?

This is about making fresh foods feel simpler and more confident – without information overload.

A helpful resource for vets and pet stores (as well as pet parents)!

The Selective Nutrition Guide App is built first and foremost for rabbit and guinea pig pet parents – and it can also support professionals who advise them.

  • Veterinary teams can share a consistent resource that clients can revisit at home (including feeding routines and body condition guidance).
  • Pet stores can use it to help customers understand everyday feeding basics and feel more confident when choosing a diet for their rabbit or guinea pig.

Important note for homes with both rabbits and guinea pigs

Some households have both, although we always recommend keeping them apart – rabbits and guinea pigs prefer the company of their own species.

The app supports both rabbits and guinea pigs, but guidance should be followed separately, using the rabbit sections for rabbits and the guinea pig sections for guinea pigs, so recommendations stay appropriate for each pet.
