BROWN RAT or COMMON RAT
No interactions present.
What lovely beady eyes. Is he in your garden?
I have a large compost heap at bottom of my garden.
The population grew till man next door got two cats. No more rats. They are a pest, but photogenic.
You can be reasonably ceratin that addition cats led to elimination of rats, was pure coincedence, not least because very few cats will even consider taking-on an adult rat.
Domesticated, they make almost unbeatable pets, not least for young children. But wild - they cause too much damage and carry too many diseases.
About one third of all wild rats carry Weil's disease/leptospirosis/rat-catchers' yellows. This is EASILY transmitted to man (and dogs), as it is carried in the urinary tract of the rat and hence is trailed wherever it goes. It is NOT treatable if contracted - treatment is only symptomatic. I know one person who died from it, another who lost his kidneys and a couple of others who have been permanently debilitated by Weil's disease.
Be EXTREMELY careful wherever rats have been, preferably handle that bowl with gloves and thoroughly disinfect it and GET RID OF THE RAT and remove access to any food.
I read somewhere that Water Vole's may also carry Weil's disease.
