SO, VISITING Australian Sue Hayward is shocked by the number of rats seen on Southampton Common.

Might I suggest that it may have something to do with the fact that people picnicking there often leave their discarded food and debris behind when vacating.

If we humans were better at cleaning up after ourselves then rats would not be so prevalent.

We only have ourselves to blame for the rise in vermin, everywhere.

Unfortunately, until lazy people learn to be clean and dispose of litter properly the problem won`t improve.

Educating seems to fall on deaf ears, and although anti littering laws are in place, there is no one in authority willing to implement them. Too much trouble.

Rat infestation doesn’t appear to be a priority on the councils bucket list, so the number of rats will only increase and the problem get steadily worse!
