This enclosure is one of the dedicated indoor environments we currently provide for Hugo, and we hope in time it will also house Worm, our newest primate, as a carefully assessed companion. Social pairing is essential for marmoset welfare, and any introduction process must be gradual, structured and professionally managed to ensure compatibility and wellbeing.

When we move to our new premises, we will be developing a purpose built enclosure designed specifically for primate welfare. This will include increased vertical height, expanded usable space and secure outdoor access to allow natural light exposure and environmental enrichment opportunities. Our long term aim is to ensure that both Hugo and Worm are housed in a setting that not only meets licensing standards, but exceeds them in line with best practice for primate care.

Space alone does not guarantee welfare.

Marmosets require structured environmental enrichment that encourages natural behaviours including foraging, scent marking, climbing and social interaction.

Enclosures must include:

• Natural branches of varied diameter
• Ropes and suspended pathways
• Nest boxes and sleeping chambers
• Deep substrate for foraging
• Rotating enrichment items
• Safe planting or foliage simulation

Feeding a marmoset is not a single morning task.

They require multiple feeds across the day to replicate natural foraging behaviour and to support metabolic health.

A balanced diet should include:

• Species specific formulated diets
• Fresh vegetables
• Controlled fruit portions
• Protein sources such as insects
• Vitamin D supplementation where appropriate
• Access to clean fresh water at all times

Improper nutrition can lead to serious health conditions including metabolic bone disease, obesity and immune dysfunction.
