FeVer is a good marketing name...like if he is to bring out a clothing range or cologne or whatever his plans were i think FeVer is great for that! but to actually call him that is just weird...unless your trying to be fangirly and your holding a sign that says something like "Nando gives me FeVer" ...but then i still think thats weird.
nando is much easier except it reminds me of chicken, so i too prefer to call him Fer which is easy to say and its 3 letters long and im lazy with names and will make a nickname out of anything to save having to say/type full names
cute bunny by the way, i have one aswell her names...Bunny original name huh? she has an eye infection atm though and she ate the lino in her cage which im guessing isn't a good thing for her to do
