I think one (possible) mistake I made was this:
In some cases, the forms and such say "Pets Allowed". However, I had said "do you allow reptiles?", to which, they replied "no, not reptiles".
In some situations, they only specify "no reptiles" if you ask. In theory then, this would be a loop-hole, as the paperwork simply says "Pets allowed" and may have exceptions/restrictions for pets (usually dogs) over 25lbs, but does not specify anything about Herps/Amphibians/rodents/etc.
Dare I say, I could use that to my advantage? Or perhaps just go the route of paying the $100-200 pet deposit and the extra $15-50/mo they tack on to the rent, without specifiying what type of pets? (Or only specifiying the cats only, and claim to have gotten the herps later/pleading ignorance/something...else).
Again, I'm not going to live in a place the explictly says "NO REPTILES" with my herps, but maybe go with a "don't ask, don't tell" about the herps and only offer up the info on the cats.
