The threads are usually open for a week at a time, but sometimes they close earlier if there aren't enough pets to keep the thread(s) open. We try to keep a minimum of 5-6 pets up for a thread to stay open, mainly to prevent members from getting swamped with requests. But the threads that do make it to staying open the entire week are either closed on Sunday evenings, or new pets replace the previous ones at that time. The critical thread will stay open until Sunday as long as we have 6 or more pets up on the thread. So you will have until then to make new requests.
I hope this answers your question
