There is nothing to see there, sorry
There is one near Palermo (in Carini), so in the North West, called Bioparco di Sicilia, but it is nothing special
The better are in the North and Centre, while the biggest (never been there by the way) is in the South (Puglia)
The best is the one near Verona (in Bussolengo) called Parco Natura Viva, then also Zoom Torino (Immersive zoo), Parco Zoo Punta Verde, Le Cornelle... are really good ones, but they are in the North
