Really good news that the bowls are a safe metal to use. Sounds like hubby is a bit of an expert. Totally agree re. the spammers. How boring sending hundreds of messages, especially to somewhere they are unlikely to even be read!
Hope the hogs there are doing well. I have a new, fairly small, hog visitor the last few days, but no sign of any hoglets yet, but I don’t have as many females visiting as there use to be.
