Male kittens are usually neutered at between 4 to 6 months of age. However, the AVMA has endorsed early age neutering of dogs and cats 8 to 16 weeks of age. You and your vet can decide what is the best time starting in a few weeks.
The use of incense was very common. It was employed for profane purposes as an antidote to the lassitude caused by very great heat, as perfumes are now used. Mention of its introduction into pagan worship is made by classical writers (cf. Ovid, Metamorph., VI, 14, Virgil, AEneid, I, 146).
It is employed to preserve foods, to make powdered incense burn more evenly, and as an ingredient in Gunpowder (which is Saltpeter, Charcoal, and Sulphur.) It also has a reputation for diminishing the male sex drive when ingested, although this is not backed by scientific evidence.
