Virgo (Aug. 23-Sept. 22) — Virgos are known for their practicality, cleanliness, and need to stay away from chaos. Being a clean-freak doesn't really work when you have an animal in the house since some pets shed, traipse mud through the house, or cough up fur balls on the couch. A Virgo pet owner will be loyal and can create a deep bond, but there are few pets that a Virgo won't be too critical of.
Pisces (Feb. 19-March 20) — Pisces can be a little uncommunicative and all over the map when it comes to feelings. Not even a pet wants to deal with an emotional wreck.
Sagittarius (Nov. 22-Dec. 21) — Having a pet is a huge responsibility, and this sign is known for being a little irresponsible sometimes. A Sagittarius pet owner loves their freedom, and since pets can't take care of themselves, this sign might want to hold off on getting one.
