For Port lympne, small cats are best late in the afternoon, I often stay around Carnivore Territory till closing time. Apart from the Scottish Wild Cat and Black Footed Cats, all the small cat enclosures are relatively near each other.
Big cat viewing is relatively easy all day, a part of the park that is quite well hidden are large carnivore enclosures that are very near the entrance. As you are coming out of the gift shop/entrance, turn right and follow the path and there are some Barbary Lion, Amur Tiger, Cheetah and Wild Dog enclosures.
The "Bengal" tiger/lion enclosures down at carnivore territory tend to be harder to see their inhabitants. They have lots of small cats off-show at the moment, and I'm not 100% sure if the brown hyena is still there, if he is, then you need to book to see him.
Port Lympne is much steeper than Howletts, which means walking around it for a day can get very tiring. The ratels at Howletts, on all of my visits, tend to be active for a lot of the time but more so in the afternoon. I find animal viewing at Howletts much easier, with the exception of small cats, mainly due to there being more glass enclosures.
Are there any other animals you are particularly keen to see? Hope this helps
