I agree, in principle, with your views on visitors feeding animals although the details you provide are not strictly accurate.
The famous gorilla “Guy” died in 1978, but London Zoo actually banned all visitor feeding ten years prior to this is in January 1968. The ban was introduced because the African elephant “Diksie” died after falling into the moat in 1967.
You are correct, feeding was banned after Diksie fell in the moat, not after when Guy died,did Dicksie fall when attempting to take food from a visitor or was she pushed into the moat by Lakishmi, or perhaps a bit of both?, I realised my mistake yesterday, you have confirmed it!, I do think however I am correct in stating that Guy had tooth decay caused by visitors feeding him. Going off on a tangent now so back to South Lakes, it certainly has character, perhaps they have too many species crammed into the zoo at its size at present, perhaps if it is fortunate to expand this will remedy the situation as long as they don't just cram more animals in and make it more spacious and perhaps a better quality of animal housing. I certainly agree that everyone should visit themselves and draw there own conclusions from it, one thing I will always be grateful to South Lakes is realising what a fascinating animal the babirusa is, I hadn't really taken much notice of them before at other collections but I recall scratching one behind the ears just like a pet pig some years ago, a keener interest in this species resulted in this.
