You dont really need to have a lot of cakes their food doesn't go down as fast as other people said just make sure u have a least 5 cakes in fridge that eill be good for around 5 snails yeah all depends on lvl of snail try to tame the highest lvl u can and just let that cement paste flow :)
Starve taming doesn't work too well for 2 reasons
1. It's food bar may be small, so it may start losing health before it even gets close to tame time.
2. The cool down gap for eating cake, means that you need to factor in the eating time.
Hope this helps
