You are going to run into some serious problems with your target and the Anafi's low resolution FLIR Lepton sensor.
This time of year the cat is going to be the same temperature as a lot of the background you are looking at.
If the cat is blocked by leaves, and branches the thermal will not be able to see the cat unless there are gaps in the leaves and branches. Thermal does not see through things like the movies.
The Lepton sensor has a hard time picking up people at anything over 100 feet, so the cat will amplify this.
Scenarios where the Anafi could see the cat are probably going to be the same scenarios where you would see it on the RGB camera.
Here are some RJPEGs taken with my Cat S61 phone which has the same exact Lepton 3.5 sensor in it.
Image 1 - There's a large crow under the spot meter. Only MSX helps to see it. Taken at 75 feet
Image 2 - There is a person walking by on the sidewalk obscured by trees. I have no idea where he is, but he's in there. Taken at 75 feet
Image 3 - There a person directly below the spot meter. Only MSX helps to see him. Taken at 75 feet
Image 4 - There's a person in the spot meter. The resolution here is hurting really bad. The spot meter is made up of 10 pixels, and since they are such large pixels they have temperature data in them from not only the person by also his surroundings.
Image 5 - In the shade under the tree you would most likely see the cat at 75 feet, but then again your RGB would too.
We also tested the Anafi Thermal at work. We had a lifeguard swim out and tread water. We placed the Anafi at 150 ft AGL and tried to see the lifeguard. We could not. A vendor then hovered near us with a Matrice 210 with Z30 and XT2 640. We could see the lifeguard's fingers or should I say finger LOL.
If it was cold outside and you kept under 100ft AGL and the leaves were off the trees, you would have a decent chance finding the cat if it was in the woods. This time of year you would need a cool summer night and luck to find it.
