I do prefer dogs as they are more friendly. I have been in units in which the cat urine is so bad it stings your eyes.

Dogs are great.  To cats, I used to be indifferent, and then moved into a place with cats.  Never again.  Never.  Ever.  Again.  I now hate cats.

I would have to say Dogs. Well trained, adult dogs as long as they are not a nuissance to other neighbors and it helps if I know the animal..but do not discriminate.  I do thorough reference checks, background checks as well, and get the previous Landlord's opinion about their experience with the Tenant having the Animal, more importantly how they were as a responsible Tenant. I do have a Tenant with a Cat though. So far no problems or concerns but in my heart...dogs. All my Tenants have a non-refundable deposit, and automatic Carpet Cleaning Fee upon move-out. Interesting Question. Have a great day, Bob!

Dog lover here. I had a "responsible" cat owner in one of my furnished rentals that clawed and destroyed a $5000 leather sofa, 3 leather chairs and a leather ottoman. Never a cat again!

Our rental condo is in a complex that doesn't allow pets. The few that do usually limit it to one cat or a small/medium-size dog. I like both but the difficult removing odor from cat urine is a concern.

Most rentals in HOA's here do not allow animals by renters however, the unit we owned did. 

I like both and have both as pets. I don't like renting to anyone with pets...dog or cats or otherwise. Not everyone is a responsible pet owner. 

No pref.  No pets

I am a pet lover. I have had cats, dogs, and birds. I love them all. Right now we have two beautiful cats. As a landlord, I would have to say no to all pets. They all cause damage in one way or another.

We allow both but take non-refundable pet fees adn don't want any huge or vicious breeds. People's pets are their families.

DOGS! Dogs, dogs and pretty much any kind of dogs.  Cats make me sick - and we have had some severely damaged homes because of a cat's urine issues.
