Hi Hupie
Yes, you are right, I did work in Dublin Zoo (although zoo keeper may not be the correct term!!) I was a volunteer for about 6 months, helping out in various sections, before I had to return to the UK and had the great privilege of working with my gorgeous friend in your photos. I do remember you from the Zoosite forums but I didn't do very well with learning Dutch & the online translators are rubbish so when I found this site I thought I'd ask around here!
I did get to visit Sibu last year & he did seem to remember me (he was a bit like the other Sibu but with redheads I think!!) I keep an eye on the Ouwehands website & there are usually some photos of him there but since they updated the site there hasn't been any new ones & I was beginning to worry that he'd moved on again.
Hopefully if he is still there, I will be able to get back to see him again maybe in August or September.
Thank you so much for your help again!!
