The lions and tigers at the Bewdley-based attraction have been taking dips in water pools to keep cool during the 30C temperatures.
Meanwhile other animals – including the Safari Park's giraffes, lemurs and meerkats – have been enjoying tasty frozen treats.
Keepers have been busy making handmade ice lollies, which are a mix of frozen water and some of the animal's favourite foods.
The simple treats help to cool the animals down – and also provide some fun enrichment during the long summer days.
Angela Potter, head of wildlife, said: “A huge part of our roles as keepers is providing the animals in our care with varied enrichment. This is very important, as it helps enhance the quality of their environment and care, as well as satisfying their behavioural and psychological needs. Different forms of enrichment involve food, sensory, social, cognitive and physical attributes.
“In particular, when we experience weather such as we have over the past week, enrichment activities are a vital way for us to ensure our animals are keeping cool and for us to support them regulating their temperatures.
“Whether it’s moving daily feeds nearer to water pools as we do with our carnivores, or making tasty ice lollies for our giraffes and smaller animals to enjoy; it’s not only a vital measure to keep our animals cool, but also a great source of fun for everyone to see our animals enjoying the summer sunshine.”
