Our furry family of possums has promised to eat as many cockroaches and other Bugs and snails as we will let them! They do NOT carry rabies (their body temp may be too low) and they are not aggressive. They will ignore your cat (the feeling is mutual, my cats don't mind them a bit).
Yes, their tails loot like rats but these guys are very sweet. We even have a mom and baby. Please let them be.
