Hi and welcome to gothicat World, i hope you will like it here
!
The gender does not effect the pet's outcome, it is an option to personalize your pet such as its name or its current living place (to change these options go to one of your creature's profile and click on "Infos", there you can change its gender, its name, its descripiton/story and its current living place, this last one will actually move your creature from one place to another so it will take some time - 3 minutes at the most, and it will lose some energy
).
The 4/4 means that your creature is the n°4 out of the 4 different creatures for this series and this species.
I looked at the previous series page, and all is working fine in english for me.
You have to click on a species image on top of the table (the first star equals all species), then on the available series for each year.
If you have an error message can you tell me which species/year/series you were trying to view so I can correct it if it's a bug ? Thanks !
If you need any more advice feel free to ask, I'll be glad to answer
PS: If you find some errors in the translation of the site you can tell me and I will change it asap
