23 grams is not very heavy at all. I have an Ortofon SPU pickup cartridge (head) that weighs about 30 grams and it still feels fairly light.
Do you mean 32 grams? A kilogram is 1000 grams, an average cat weighs 4-6 kilograms, so 4000-6000 grams. 23 grams is not very heavy at all.
23 grams is nearly the same weight as a tablespoon of sugar.
