I have a little Chihuahua (sp) and it does not take him long to go out and do his business.. when he comes back in he finds the nearest ac vent and plops down on it.
I have had to keep adding cages on top of cages to help hold mine in place.. plus I have had make taller stakes. I have only gotten one ripe tomato off so far... I have been pulling them and frying the green ones..
