Including fosters, I have had 7 off the top 10 list, but none off the unusual list. Think the most unusual foster was Sonny Jim (now renamed Samson). The only one of my fosters I have renamed so far was Swiggy, normally I just keep the name till they get rehomed, but couldnt live with that.
I did have a slightly humerous conversation at the vets last year - I had 2 appointments, one for Zia, and one for Mia, and I Was booking in a new foster to be spayed - she was called Tia. Luckily Tia was a different colour, or that would have been really confusing, as Zia and Mia were both dark torties.
