I love this guinea pig shelter however on not a particular warm dad i placed a thermometer inside at 18°c and returned 1hr later to see the temperature had gone up to 26° which is way too hot for a guinea so please be warned do not use these in the heat even on cooler days. They are lovely and well made there is a lip underneath that catches debris so that can be awkward to clean but other than those two issues the heat being a major one it is a nice safe house but for winter not sure how they will cope with condensation build up!
