The picture was taken at the Schoenbrunn Zoo in Vienna by Romashchenko Elena, a maths teacher. She said: "I noticed how a little monkey was sat on the goat’s back and was surprised the goat wasn’t annoyed. The monkey started looking through the goat’s fur with its hands. I presume it was eating any sort of ticks or fleas. Perhaps that’s why the goat was happy to have the monkey on its back."

Spring has sprung: John the baby goat makes friends with Charlie the chick at Reddish Vale School Farm near Stockport
This newborn chick, who is just a few weeks old, has apparently struck up an unlikely friendship with a kitten who helps protect her from pesky vermin. Sergey Dmitriev, from Barnaul, Russia, said: "We want to help restore the ancient Pavlovskaya hens because they are a very rare breed. Sometimes they can get attacked by rats and mice who get into the coops and kill them. We usually have to protect them like they are our own children – but recently our pet cat Mikeal has protected them for us. He will follow them everywhere they go whenever we let them out to make sure they are safe."

Alison MacLean of the Edinburgh Zoo meets a young Giant Panda at the Bifengxia Panda Centre near the city of Ya’an in Sichuan Province, China.

Tian Tian translates as ‘Sweet Honey’ and Yang Guang as ‘Sunshine’.

At 85kg, black Labrador Sampson is so overweight he cannot be safely exercised. His bulging blood-shot eyes are caused by fatty tissue around his head and high blood pressure. The dog, 42kg above his normal weight, is so fat and unfit that Animal Aid staff fear it will take him until Christmas to shed half his massive frame. Sampson has to be transported to a Melbourne shelter in the Animal Aid van for his weekly weigh-in because he can’t comfortably fit on the back seat of a family sedan. "He’s the size of a small heifer," Animal Aid veterinarian Amber Lavery said.
Ros Boisseau leads Mog the cat through a swimming session at Hawksland hydrotherapy pool, near Wadebridge, Cornwall. A cat that was left with both front legs completely paralysed following a horrific car accident is learning to walk again – by taking swimming lessons. Mog sustained horrific injuries and spent six weeks on a drip after a car smashed into him in a hit-and-run incident in February. A local vet suggested that hydrotherapy classes – usually for water-loving dogs – could help relieve his pain and Mrs Ashworth decided to take him for a session. Mog initially "looked horrified" when he clapped eyes on the canine hydrotherapy pool – but took to it like a duck to water and began swimming lengths.

A tiny reed warbler feeds an enormous cuckoo chick, thinking it is one of its own babies. The family was captured on camera by wildlife photographer David Tipling near Thetford, Norfolk. He said: "Cuckoos have the ability to lay eggs that closely resemble the coloration of other birds. Once this young cuckoo hatched he would have pushed the other eggs out of the nest and started demanding food. These reed warblers appeared to think the chick was their own – it was just their instinct to look feed it. The cuckoo was three times the size of them but they didn’t seem to notice."
