A popular Lancashire zoo has come under fire for choosing to remain open during the UK heatwave - but they have come up with innovative ways to keep the animals cool.

A red and amber extreme heat warning has been issued for Lancashire with highs of 35°C expected in parts of the county.

The weather warnings will be in place until midnight on Wednesday.

Chester Zoo said it will be closed on Monday and Tuesday “for the safety of our staff, visitors, animals and plants.”

However, Blackpool Zoo, has decided to remain open despite an amber weather warning being in place for the coastal town.

Their decision has sparked disappointment among some customers.

In a Facebook post they said: “It's going to be hot over the next few days.

“So, if you're planning on visiting us, don't forget your sunglasses, sun cream and hats, take time out in shaded areas and remember to stay hydrated."

Sarah Mundy said: “I really feel like you should be closing for Monday and Tuesday like Chester Zoo.

“I’m very surprised that you’re going to be open,” said another. “Chester Zoo is closed to protect the animals and staff.”

Another said: “Chester Zoo and Yorkshire Wildlife Park are both closing Monday and Tuesday so animals can shelter and so staff can focus on keeping the animals cool.

“Blackpool Zoo should follow their lead and close in the best interest of the animals.”

Another person said: “Please think about the safety of your staff and also the chances of putting additional stress on the NHS.”

Darren Webster, Zoo Director at Blackpool Zoo, said: “The health and safety of our animals, staff and visitors is always our highest priority.

"The Blackpool area is not covered by the Met Office’s red weather warning and we are planning to remain open this week.  

“We advise that anyone visiting us wears sunscreen and a hat and stays hydrated.

"We are providing extra sun protection, additional rest breaks and water to our hard-working keepers and staff.

“We are fortunate to be situated in 37 acres of mature parkland, so there are plenty of shaded spaces for people, and our animals, to enjoy. 

“We have various indoor misting systems and cool air fans for the animals and many have their own swimming pool. 

“Anyone with pre-booked tickets for Monday and Tuesday can change them to another date if they prefer.”

Zoo keepers have also come up with some clever ways to keep animals at the zoo cool.

Darren said: “Keepers have come up with some ingenious ways to keep our residents cool including sprats on ice for our sea lions and penguins, frozen fruit treats for our primates and regular showers for our elephants.”

Sea lions have been tucking into chunks of ice filled with fish and ring-tailed lemurs have been given frozen fruits instead of their usual apples and orange slices.

The zoo’s herd of six Asian elephants have also been splashing around in the outdoor swimming pool at Project Elephant to keep cool in the hot conditions.
