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).
Stick incense is probably the most common form. The gum or resin from which it is made coats a long thin stick that burns slowly, releasing the particular fragrance that it contains. The stick type can also be solid so there is no stick center or core, only a solid chunk of material.
