According to “The Renting With Pets: A Tenant’s Guide”, tenants should prepare a pet resume, including references and an introductory meeting with the landlord. My understanding is that if the landlord forges a good relationship with the pet then the tenant gets the all clear. This can be difficult though with some animals.
It largely depends on the type of pet. If you have a few goldfish in a tank it won’t be of nearly as much concern as a rampaging spaniel with a penchant for wooden furnishings. Things with sharp teeth usually cause the most concern and whilst most of them remain in other continents, the British bulldog is definitely a pet you do not want in your property.
How does an introductory meeting work? In my head it comes across as some bizarre interview. Whilst dogs are of the conversational variety I’m not sure how much intellectually stimulating conversation you would get out of a fish. You could have a few seconds of deep and meaningful eye contact, assuming the fish is actually looking at you and isn’t daydreaming about that new ship wreck it has been promised.
Meeting a pet once and trying to gauge how they will fit into the property is ludicrous. Pets react differently in different situations so there is no way to authoritatively say this pet is well behaved etc. A pet resume and referencing are just needless bureaucratic processes that will neither ensure a tenant’s pet will behave or that the landlord accepts them.
