I definitely like cute animals. So I try to generate them with AI Art Generators. Here are some examples:
Here's a kitten holding a red heart, created with Full Journey.
Full Journey once was Bluewillow AI. You get 4 images with one prompt, and you can use the images commercially. Full Journey is not totally free - you are paying for each prompt with one credit. However your credits are filled up to 50 every month or so. The quality is quite nice, and you can choose the aspect ratio.
This cute lioncub was created with Nightcafe Studio. Nightcafe Studio is not free either. You pay 1 credit for one image. However, you can earn additional credits: You get 5 credits for logging in, 3 credits for publishing your image on instagram, 2 credits for voting in the daily challenge. In addition to that you get 5 credits for every five images you create.
The creations can be used for commercial purposes (for example as designs on print on demand websites).
The third example of a cute lioncub was generated with Bing Image Creator. Bing only offers 1:1 aspect ratio. At the beginning you could read on the website that commercial use is not allowed; in the meantime it looks like there is no such explicit restriction anymore.
Bing is free for anybody who has a Microsoft account. You do not have to pay any credits; you have so called booster points which help to generate your images faster. You can also earn additional booster points by answering certain questions.
