What to expect in the first 24 hours post-vet
Your cat received treatment for grayanotoxin exposure, but these toxins disrupt nerve signals for hours after ingestion. Even with veterinary care, watch for slow blinking, reluctance to move, or sudden head bobbing—these suggest lingering muscle weakness. The 4 kg body weight means small amounts hit harder; ten leaves are enough to require close tracking of litter box use and water intake.
Check gum color every few hours by lifting the lip gently; pale or bluish tints mean circulation issues. If she squints in bright light or stumbles when jumping down, note the time—neurological signs can reappear as toxins recirculate. Keep her in a quiet, dim room to reduce stress on her nervous system.
Critical hours 24 to 48 after ingestion
Though peak danger passes in the first day, delayed heart rhythm problems sometimes surface later. Feel her chest behind the left elbow: a normal cat pulse is 140–180 beats per minute—if it feels sluggish or irregular, wrap her in a towel and head back. Tremors that start now are more concerning than early ones, signaling possible organ strain.
Offer wet food mixed with water every four hours; refusal could mean nausea or mouth pain from earlier vomiting. Hydration matters doubly after clinic fluids wear off. If she pants while resting or leaves wet paw prints from sweating, her blood pressure may be dropping again.
When to interrupt monitoring and return to the vet
Any seizure-like activity—even just one stiffened leg—warrants immediate transport. For small cats, mild twitches can escalate fast. Similarly, if her third eyelids (pink crescents) stay visible over her eyes for over ten minutes, her body is struggling to compensate.
Record breathing rates while she sleeps: more than 40 breaths per minute or less than 12 needs evaluation. Bring any leaf fragments you find in vomit or stool—their freshness helps the vet gauge toxin release timing. Avoid using heating pads; temperature swings worsen cardiovascular stress.
Longer-term recovery signs to track
By day three, she should regain her usual litter habits—straining or avoiding the box hints at kidney irritation. Play-test with a feather toy; hesitation to pounce may reflect residual muscle soreness. Brush her daily; excessive hair loss or dandruff can follow toxin-induced metabolic shifts.
Weigh her weekly for two months; unexpected drops could signal thyroid disruption from the poisoning. Future bloodwork should check potassium levels—grayanotoxins sometimes deplete it gradually. Until then, skip treats high in sodium, which can exacerbate lingering heart effects.
