I used to have four bears (Cheri, Stitches, Groucho and Tammy) until Groucho and Cheri moved out. I now have two bear cubs and two wolves (Freya and Skye).
I've currently got 5 cats and 2 deer, but I'm hoping to balance that out in the future! I'm thinking right now that I'll do 2 wolves, 2 cats, and 3 deer, but 3 of anything feels a bit excessive... so I guess we'll see where I end up! I like the towns that are full of the same species, but I wouldn't want one myself - I like diversity! :3
I have 2 ducks and 2 deers. The most villagers I've ever had that were of the same species was four. I had Diana, Fuschia, Zell and Lopez. Now I've just got Diana and Fuschia.
Gizmodo, I blame you! I had nothing for or against sheep villagers before I joined this forum. I have Wendy in my main town (the one I play in real time) and I think she's great. I'd be very recluctant to let her leave, but she's never asked to go yet, so I won't worry about that now. In my second town I have Vesta and will have Frita on Saturday (if the other person comes through and let's me invite her to my village). I'm on the look out for Pietro, too, and I'll likely have him soon. Two villages, four sheep. Add them to my three octopus villagers and I can have nearly an entire village made up of nothing but sheep and octopi. My fondness for the octopus villagers is entirely my own doing, but my new obsession with sheep villagers is entirely Gizmodo's fault. Before your posts, I was unaware of the many sheep villagers and how awesome they are.
Funny, when I started the game and I had my first nine villagers, I had two monkeys (Shari and Deli). One of them had to go, I didn't want two of the same species when there are so many available. Now, we're almost two months in, and I'm going in the opposite direction.
I've got three sheep as well: Wendy, Vesta and Frita. I've also got two squirrels: Filbert and Blaire. I like all of them but I'd still rather have more variety in my town.
