Naturally tasty and healthy

Selective Naturals FibaFirst combines long chain fibre with essential vitamins and minerals to create a unique diet that caters for the natural feeding behaviour of rabbits. FibaFirst is rich in natural ingredients and is made in a simple and uncomplicated way.

The average rabbit (weighing 2.5kg) will require 75g of Fibafirst per day (30g of food per kg of body weight per day), although because Fibafirst has a nutritional profile that is similar to hay, it may be fed freely, however weight should be monitored regularly. We would recommend feeding your rabbit their pet food twice a day – once in the morning and again in the evening. A small handful of suitable fresh vegetables should also be provided along with good quality hay and clean drinking water.

No runny poo!

4th April 2022

The high fibre content of Fibafirst has made such a difference to my rabbit. Her digestive health is so much better, with no runny poos at all. Won’t be going back to the mix I used to feed her.
