Please help my sweet boy

Hi my name is Taylor, I have an almost 2 year old orange tabby male cat named ziggy, he is the most precious kitty and he means the world to our family.. two days ago we woke up to him not eating or drinking, and he is very lethargic, now he isn’t using the washroom and is dehydrated I need to get him seen asap

i currently don’t have a income and two small kids, I don’t have the money to get him to a vet, I just need to raise enough to get him seen so I can find out what can be done for him, any donations are appreciated as this is an emergency he needs a vet asap.
