There is no such a thing as technically when you sign a lease, you either break the rules or you don’t!
If your landlord was to find out that you were residing on his property with so many animals and that this was a breach of the lease agreement, he could
A# Make you get rid of every single one of them
B# Evict YOU and all your animals
This is serious, all it takes is one person to complain to your landlord, like your future ex-roommate for example!
And if something like that was to happen imagine how hard it would be to find a new place to live in!
