The serval is a medium-sized cat but I didn't really know what to expect before we got there. They look like normal domestic cats just a lot bigger with much longer legs. Servals grow to about 59 to 92 cm in length and stand about half a meter tall. This boy was in a very playful mood and had a ball chasing the handler's scarf. The rest of us, well we were clicking away through the fence as they wanted as little interaction with other people as possible.
