I have an important decision to make hopefully I can get some of your advise and opinions. I have been seeking an adult Russian and did find a very nice 6 year old from a very reputable and experienced breeder. All the sudden last night someone from my area responded to a Craigslist add I put on a couple weeks ago and wants to rehome her russian. She thought it was 5 yrs old but bought it from a pet store full grown, I informed her she's prob much older but according to her, no health issues what's so ever. Here are some pics, can anyone estimate an age? What do you guys think I should do?
