So far so good. Last night a hedgehog entered the hedgehog house to eat some of the food I had placed in there. It looked to be a bit of a squeeze but it managed OK. As far as I can tell there were two different hedgehogs visiting early last night though only one entered the house. One thing I had forgotten - hedgehogs and plastic saucers don't mix. They always end up tipping the water out. Now replaced with a heavier water bowl.
I'm glad they came early as it kept snowing on and off though there is only a thin layer this morning. One long range weather forecast I read yesterday said that we can expect these low temperatures for another 15 to 20 days! At the time of writing (7 a.m.) we are getting a heavy snowfall. Looks as though someone needs to write a new song - I'm Dreaming of a White Easter.
When I checked the overnight video recording I could see that the cat had tried several times to get in the house but failed every time. So far it looks as though the simple modification to the entrance has done the trick.
Checking the contents of the house, the hog had eaten the crushed, unsalted peanuts and dried mealworms but not the dog food.
