| The sanctuary is already home to 166 animals and is in the process of constructing new habitats for some apes that were on their way into retirement before the latest NIH decision. | |
| "At the earliest, it would take between three and five years before Chimp Haven would be ready to take in more animals," said executive director Cathy Spraetz. "That's the most aggressive scenario." | "At the earliest, it would take between three and five years before Chimp Haven would be ready to take in more animals," said executive director Cathy Spraetz.
