Dirty llama has no option to clean. :(

@elvici I downloaded and placed your clinic. I then had my vet Sims purchase it. They also 'lived' in it. (Interestingly, the beige llama automatically came with the lot apparently!) There was the option on the coop to purchase chickens, though it came with 4 that appeared in the fenced area as expected, but on the shed the only interactive interaction I get with the llama is to 'call over beige llama'. 

Your shed was placed mainly outside of the lot, which I believe was the issue, per my previous post:

I tried a lot of things, and none of my tricks fixed the llama, and I could not get the pie menu option to clean the poor dirty, bugged out llama.

In the end this is how I got the 'clean' option back:

1. I deleted the fencing around the llama area and the curved deck area to provide as close as possible to the default 'footprint' of the shed (the green area it requires to be set on).
2. I moved the coop to the other end of the back yard.
3. I deleted the shed, which put the llama and shed into the household inventory.
4. I activated MOO, since the shed's footprint is still larger than the cleared out area provides.
5. The llama could not be re-added to the lot, but I was then able to re-add the shed to the lot. I placed it 1/2 tile into the lot's grid area (see screenshot) to provide close to the amount of space the footprint wants.
   
6. In live mode I then clicked the shed to add a llama.
7. I was then able to get the interaction to clean the llama in the pie menu:
   

You may or may not still have issues appear with the llama since the shed's footprint is still somewhat clipped and I used MOO to add the shed (please see my previous post about the issue I had on my lot before), but you could try it for a while and see what result you get. The llama should not need fencing since I don't believe they leave the lot or are threatened by any predators.

Remember that your llama will need daily care to survive and be happy. Your clinic is super-cute, btw. ❤️
