So they are both named Sid by their previous owner: Good Sid and Bad Sid. Since they were babies they always showed an affinity for one another so the prior owner never separated them. Good Sid is the friendliest while Bad Sid prefers Grammy and will knock stuff off the tables and mantle sometimes. He is a bit mischievous hence the name.
Price is negotiable for the right buyer. They would make an awesome addition to almost any house but prefer someone with experience.
