With flamingos, meerkats, lemurs and so much more, the attraction known locally as the Bunny Park, has certainly outgrown its nickname.
Taking our cameras through the gates of the zoo, we discovered just how many animals there were waiting to say hello to visitors.
Hanwell Zoo , formerly Brent Park Lodge, reopened its gates to the public on April 1, with the introduction of a small entry fee of £2.50 for adults and £1 for children over three-years-old.
The zoo says the fee is required in order to keep on top of the rising costs in maintaining the facility.
Zookeeper Bo McKubben said the public have been responding well to the introduction of the entrance fee.
He told getwestlondon: "I think everyone understands, especially in the current climate, just how expensive things can get and just keeping a pet can be quite expensive, let alone the amount of animals we have here.
"We have nearly 300 animals here at the moment, so simply just feeding them is an expensive endeavour."
One of the most popular new additions are the beautiful Peruvian flamingos, who have certainly made the duck pond that bit more colourful.
The birds are aged from one to 18-months-old, and have travelled down from Chester Zoo.
"They are a wonderful addition to the park" said Mr McKubben.
Adding: "They have been a steep learning kerb for all the keepers here, they are a very specialised animal to keep, but they've proved very popular with the public so far."
Visitors to the attraction have been sharing their experiences on Twitter:
Other new additions include a pair of the world's largest rodents.
Two capybaras named Hydro and Tupi , have been homed in the zoo's new South American space.
Capybaras are typically 1.3metres in length and weigh up to 70kg.
Yet to join the menagerie are tamarin monkeys, frilled-neck lizards and alpacas, who are due to arrive in the the not too distant future.
Cabinet member for environment, transport and leisure Councillor Bassam Mahfouz has been visiting the park since he was a child.
He said it is a great asset to the local community: "It's on the doorstep of so many people, and with the new name, it puts it on the map.
"It's an amazing resource" he continues, "and what I've seen over the past few weeks is just so many new people are coming here and what was perhaps a hidden gem before is now something that everyone is talking about and raving about."
Of course, visitors can also meet the old favourites, namely the family of meerkats and the lemur trio of Tia, Vana and Fi.
There are also the pygmy goats, kune kune pigs and porcupines to enjoy, who appear to have grown in number.
And not forgetting the bunnies, who take pride of place outside the entrance to the gift shop.
A brand new playground featuring a sandpit and slide is also set to open, joining a redeveloped giftshop and renovated butterfly and reptile house.
