I love this thread, its so cute! I do know a lady who named her son Thomas after tom from tom and jerry. And her two younger boys were named after her friends dogs :s. My baby cousin, Alfie, is also indirectly named after a dog.
Also I once had leopard geckos named Bulbasaur and Umbreon.
That is one of the best things I've ever heard. More things should be called bulbasaur in my humble opinion.
I try to name my Guinea pigs after book or comic characters, although there have been some film and TV ones. I had Mr Pickwick, Gulliver, (huckleberry) Finn, Ultra Magnus, Ponyo, I still have Blake (after the comic Blake and Mortimer) Harvey Dent (he is a crested Guinea pig who has never been the best behaved either), Lupin and Noah.
My cat is Angel, her mum was Buffy ...
I also work at an animal rescue and rehoming center so when we get a large group of animals from a hoarding situationme and my colleague go for themes. We have had 34 Guinea pigs with Tolkien names, the avengers, x-men,about 25 harry potter names. 2 litters of Guinea pigs with star trek names as they were born just after Leonard Nimoy passed away.
We've had a few of Guinea pigs and Rabbits named after transformers, Jazz, Mirage, Bumblebee and Silverbolt. And two baby girl Guinea Pigs named Clipper and Firefly after MLP!
We also rescue ex battery/cage farm hens. I fully intend to give our next bath the most long winded MLP names I possibly can!
