Why did my healthy pet suddenly collapse?

A pet's health can rapidly degrade from acting perfectly normal to collapsing and struggling to walk in a matter of hours. This terrifying speed forces owners to make rapid ethical choices about expensive treatments that only buy a few weeks, often while veterinarians cannot explain what caused the episode.

“this morning at around 00:15 our cat has woken us up screaming (meowing) he’s a ragdoll so him signing at night is nothing new but it was like he was in pain, this meowing took around 2 min, then I noticed he’s struggling to walk seemed very confused and unresponsive, then he suddenly collapsed and started panting”source ↗

“the vet hasn’t really gave us any information on what it could be or what’s caused the episode”source ↗
