Using the IRAC Formula, research AZ caselaw and any other state's relevant caselaw or statute regarding the legal status of pets in the context of a divorce. "Pets" means dogs, cats, birds, fish, and other small domestic animals.

Draft a legal memo to me, your senior partner, analyzing the arguments for and against treating pets as personal property vs custodial figures.

Provide me with a conclusion/recommendation as to whether or not it would be worthwhile for our law firm to draft and submit a bill to the AZ legislature to lobby to change AZ law regarding this issue, setting forth those arguments with specificity.
