Animals at the Muller circuses in the face of extreme heat: Press release
Exploitation for shows
With temperatures having exceeded 30 degrees across France for several days now, One Voice is alarmed by the conditions in which animals are kept by several circuses run by the Muller family. The organisation’s investigators have observed that animals – particularly big cats – are being kept in overheated metal trailers, sometimes without visible access to water, and are only taken out into tiny cages placed on the scorching tarmac. This is a dire situation for these captive animals, some of whom do not even take part in the shows, in breach of the law.
For several weeks now, One Voice has been tracking the movements of three circuses owned by the Muller family:
- Grand Cirque Zavatta, currently in Orthez (64) from 29 to 31 May;
- Cirque Franco-Belge, based in Avignon from 23 to 31 May;
- Cirque Hartini, in Evreux from 29 May to 7 June.
Everywhere, the same damning findings.
Wild animals locked in trailers in the heat
Our investigators observed several lions and tigers locked in cramped trailers, pacing round in circles and exhibiting stereotypical behaviours characteristic of profound psychological distress. When they were let out, it was only into small wire cages set up on the tarmac, with no shade or environmental enrichment. And this did not even happen consistently… As early as April, we documented lions and tigers being kept in trailers at the Hartini-Muller Circus, as well as animals held directly on the tarmac without bedding.
Even more seriously: our teams found no water basins for some of the tigers, even though this minimum requirement is laid down by regulations and becomes vital during periods of extreme heat. In some trailers, no visible access to water bowls was observed.
These animals, who are being held illegally, should be living in sanctuaries, on grass, in the shade of trees, with space, the company of other animals of their own kind, and appropriate care. Not in metal cages turned into rolling ovens.
A family with a history of offences
The Muller family has long been known to the authorities and animal welfare organisations. In particular, One Voice has for years been monitoring the tragic situation of Jumbo, a captive hippopotamus exploited by the Zavatta Circus, whose state of health has been deemed extremely worrying by independent vets.
In 2020, Alexandre and Edmond Muller were convicted of:
- unauthorised operation of an establishment keeping non-domestic animals;
- keeping animals in conditions causing suffering;
- inappropriate housing likely to cause injury and suffering.
Despite these convictions, and despite repeated reports, nothing has changed. Worse still: the animals continue to be moved from town to town in a constant attempt to evade scrutiny, which complicates inspections and prevents any effective intervention.
Animals kept illegally, but never seized
These circuses continue to flout the law. Offences are on the rise. Young wild animals clearly born in the circus – despite breeding being prohibited – animals that do not take part in the shows, and recent acquisitions of wild animals should lead to immediate seizures. One Voice recently revealed the illegal acquisition of new ostriches by the major Zavatta Circus, yet no action has been taken.
In the face of these repeated violations, the authorities’ inaction is becoming intolerable.
The authorities turn a blind eye whilst wild animals suffocate in cage lorries. This institutional cowardice allows circus operators with multiple convictions to continue their exploitation with complete impunity. Our organisation is gathering evidence and bringing increasing numbers of legal actions, and will continue its fight until the last captive wild animal has been transferred to a sanctuary – the only acceptable outcome.
Animals are not attractions. They were not born to live confined on tarmac, behind scorching bars, at the mercy of touring schedules and extreme temperatures.
