Your example are not synonyms so i don't think synonyms.txt by itself
is going to work.
This sounds like tagging using a taxonomy. Values written to the field
storing this taxonomy could be like:
livingthing/animal/cat [doc about cats]
livingthing/animal/dog [doc about dogs]
livingthing/animal [doc about animals in general]
livingthing/animal/cat livingthing/animal/dog [doc about cats and dogs]
If you need a free text search solution rather than a metadata field
search as above you will need to pre-process your docs looking for
entities in your taxonomy and replace the entity tokens with the above
taxonomic tokens, perhaps placing these into a specialist field for
searching. A solr analysis chain which mimics such pre-processing may
get you some mileage, something like
copyfield content - taxoKeywords
taxoKeywords field analysis
tokenise
lowercase
minimal stem (sure their is one minimal english stem i think its called
keepwords [cat dog animal livingthing]
synonym replacement [livingthing/animal/cat - cat,
livingthing/animal/dog - dog, etc]
I'd go for preprocessing outside of solr but the keepwords / synonms
might work for you

I have some problems with the synonyms file, it seems i can't make it work
the way i'd want.
Here is an exemple :
I have these words : cat, animal, dog, living thing, baby shark
if i search for animal OR animals, i'd like to have the results for cat,
animal, dog, baby shark as well as their plural cats, dogs, animals and baby
sharks.
if i search for cat, i only want the results with cat or cats. Same for dog.
if i search for living thing, i want the results with living thing, living
things, animal or animals. So no dogs, cats...
So the words are in a hierarchy : living thing(s) - animal(s) - [dog(s),
cat(s), baby shark(s)]
I've tried a lot of thing but i can't get the results i want and i really
need your help :-(
