my cat is sick help

I have a 3 cats but one die a few days ago, the cause are unknown because I found him dead after coming back to school. Its sad. I thought he died because of sickness but he look like he got attacked because his left mouth side is injured. Now both of my cats are sick too(they have have the same symptoms as my late car) Yesterday they were energetic but today...Gebu (my 1 cat) sleep a lot and didn't eat fish and Dio (my 2nd cat) doesn't appear at all until tonight. I thought Gebu was full because my neighbor feed him fish. My parents got worried. My dad feed him worm medicine(English is not my first language, i dont know what its call) and Dio became sluggish. very. I bought them both inside. Gebu became a bit limp and Dio doesn't seem to move at all.

Should I gave them coconut water? but I already gave them worm medicine. What should I do? the vets are closed. Its 9p.m.
Im very worried. If you have any tips when cats are sick. Please help. I don't want them to die like their brother...

 

Have either of them been sick (vomitting)?

They could be showing signs of stress die to their brother’s death (being lethargic, tired, weak and not eating is one of the signs of stress) but if they’re not eating it could also be a digestive problem.

 

Take them to the vet.

 

Worm medicine tends to be too strong for cat hence you shouldnt really use that as the first aid...

 

OP says the Vets are closed at 9pm.
But I agree, if there’s an emergency line you can call?

 

Food poisoning is my nearest guess, I would suggest calling VET doctor asap they would provide better remedies.

 

Do you have a regular vet? Do you have their contact?

 

It's usually ends up being Dio. Not sure how internet knowledge applies in real life though.

 

For now, keep a close eye to them and bring them to the vet tomorrow morning. I hope they would be healthy again. I'm worried if it's virus that attacks cats like my cousin's

 

not been vomiting so far but coughing hard is shown. They don't eat much dry food.

 

no, since this is the first time I have sick cats

 

unfortunately no

 

if only my dad allow me to skip school, I would keep my eyes on them...but since I need to go to school tomorrow. I don't know how it will turn up but sure will bring them to vet tomorrow.

 

maybe covid-19? animals can get infected too....

 

Consult professionals regarding your or your pets health. The causes for cats not eating and being lethargic are many it could be they are sick or poisoned but it can also just be them mourning their friend

 

its green zone in my state but possibility...

 

I Hope they get better! Perhaps explain to your father so he can take them to the vet for you while you’re at school.
