Cabarceno hasn't lost many species, it maintains itself pretty consistent on this, but there are some animals that I miss:
-Some of the reptiles in the reptile house. Now, most of its inhabitants (except for Gila monsters and green iguanas) are snakes, and some of the non-snakes are missed. I remember seeing Cuvier's dwarf caimans (I think), alligator snappers and some kind of monitor.
-Blue wildebeest. They used to house a pair in the main savanna, and I don't know why they didn't get more of them, but suddenly one of them disappeared and a lone animal was left in the exhibit. Now, the last one is no longer signed.
-Sable antelope. She was the only sable in the exhibit and seeing what zootierliste says the last one in a Spanish zoo. This one has a similar case to the wildebeest, but I really liked this animal.
-Cuvier's gazelle. After the terrain wasn't sustainable to house a breeding group of these animals, the gazelles left the park, leaving just a male, which is housed in a small pen at the entrance of the park. The species hasn't really "disappeared" from the park, but it will soon.
-African wild dogs. Exhibited with the hyenas, these were one of my favourite animals in the park. I didn't have many opportunities to see them, but I used to love them.
-Warthogs. I have only seen warthogs in Cabarceno once, and it was like 10 years ago. Every time I visited the park, the warthogs seemed to be absent or hiding. Then, out of nowhere, they were replaced by gemsbok. I still wonder what happened to them.
