I've read that my dear friend Kareltje has problems because of the high temperatures. It's so hot that he even wants to take a shower; now, that's really a problem for a cat!!
I didn't know The Netherlands may have such hot summers. In fact, when I say "The Netherlands", in my mind occur:
1) ...low-lying country, below sea level; possible floods; water! Cats, save your souls!

2) Cheese! That's wonderful!
3) Tulips... romantic!

4) Windmills... adventure!


6) Rembrandt... maestro!
So, my dear friend, don't be sad!
In my country we have 38-39 degrees and nothing seems unusual!
