Small animals like cats are a 6th house matter.
Venus is your significator, located in the 6th house as a co-significator of the 6th. Virgo on the 6th house cusp is one of the dual signs, which can indicate two of something. Plus, the conventional wisdom about cats is that it is no more trouble to have two than one, and they appreciate a companion if brought in at the same time, especially if they are litter mates.
But is their something else going on here? Mercury (ruler of the 6th) has no essential dignity and the moon in Scorpio is in its fall. Venus (you) is also in detriment in Scorpio. Mercury's cusp ruler Mars is domiciled in Aries, but it is in the 12th house, and then Venus is in detriment in this sign. The sun as co-significator of the 6th falls in Libra.
Have you got a partner, or someone else who shares your living space, who really does not want you to have a cat? Possibly there is a pet allergy?
(You ask whether "we" should get a cat or cats-- presumably there is more than one decision-maker here.)
