I have recently just been inform of your guys mod "AnimalCraft" and am excited to learn more.
A few minor suggestions as I havent had a great deal of what you guys already have, but here we go,
[+] Much like a cow, add it so you can get "Goat Milk" by right-clicking a bucket on a goat to obtain its milk.
- Along with addition maybe add a variety of foods that can be "crafted" with goat milk, such as a variation of cakes, or
cheese, mainly just dairy items.
[+] To elaborate more on the "Variety of Foods", I'm aware this is a mod revolving around Animals, but it doesnt just have to relate to Animals, it could contain variety of different foods from the Animals, and maybe some cool plants like the ones we have in real life that produce vegetables and things like that to create different foods and what not.
[+] Maybe like accessories for certain animals such as a dog or wolf, there could be like a dog-bed, dog-cage, dog-food, dog-food-bowl, water bowl, etc, same for "cats" or ocelots, Cat Food, Tuna, etc.
[+] If I remember correctly you guys have a few bird related animals, I was thinking adding more variations of birds as there are millions of types in real life, regardless if you add this you should make birds tamable and add accessories for them such as a Bird Cage and things like that.
[+] Since this will be 1.7.10 add in a lot more Water Animals as in Normal Minecraft we are used to see land animals and not so much aquatic animal (Unless you have had a chance to fully play in 1.13 for some time), but if you decide to add an aquatic portion to this mod, or if you have already, I think you mentioned like a Trident as a weapon or something of the sorts so I do believe there are more aquatic items, but to add to the aquatic areas, add in like multiple aquatic plants such as coral, or sea anemone, and things like that, maybe some crabs ^-^.
I also recall that you mentioned there are foxes, can you elaborate more on them if you decide to respond to this, like what biome they would spawn in and things like that.
Sorry if many of my suggestions are things you have already added or already working on it as I don't really remember things that often
Anyways, thanks for reading my suggestions, have an awesome rest of your day <3
