Gaga Gran, there is a world of difference between rats and foxes ( I have actually had pet rats )
Rats have no bladder, and urinate constantly, so wee on anything they run over - which is why they are so hazardous to health, as many have weils diesease. They also breed prolifically , and have no natural inhibitor to breeding, unlike foxes, as they can eat pretty much everything, including faeces, and live in sewers, which obviously harbour other diseases as well . It is not uncommon for rats to enter homes, as they can come in through small gaps, unlike foxes.
A better question would have been do I feel the same about dogs - after all they kill and injure more people annually than foxes...( and probably more than rats !)
