Hey there! Is it possible that you maybe borrowed a pet or got one from the pound momentarily? If you have ever had 3 on your account at any time, it will forever change the number. But there is nothing that it will affect to be honest because that number will not go up unless you get more than 3 now.

I can check pet transfers for a bit but not anything else like if you dropped one off at the pound or anything. That only goes back a few weeks.
