I love these. Looks like the cat's getting a few dinners. Which tracker did you use? I keep looking at G-PAWS (available for under £30) but I'd like to use it

I love these. Looks like the cat's getting a few dinners. Which tracker did you use? I keep looking at G-PAWS (available for under £30) but I'd like to use it on the dog too and he'll take it into ditches and ponds. I suspect "weatherproof" won't cut it.
