If drainage is mandatory, limit it to 1\/3 of the total volume.<\/li>\n <li><strong>Pleural (Chest) Fluid Rule:<\/strong> Fully drain thoracic fluid via ultrasound-guided thoracocentesis (chest tap) to relieve life-threatening dyspnea.

After 3 hours, the medication is safely absorbed.<\/li>\n <li><strong>Diarrhea:<\/strong> Manage with therapeutic probiotics (Fortiflora, Proviable, Pro-Pectalin) or pureed pumpkin (1-2 tsp twice daily; avoid pie fillings with onion\/garlic toxins). Low-dose Metronidazole can be used safely if prescribed by a veterinarian.<\/li>\n <li><strong>Hypothermia:<\/strong> If a cat's temperature is low, provide a hot water bottle or incubator. <em>Never place a weak, non-ambulatory cat directly on an electric heating pad due to severe hotspot burn risks.<\/em><\/li>\n <\/ul>\n <\/div>\n <\/div>\n\n <div class=\"fip-grid-banner\">\n <div class=\"fip-grid-banner-col\">\n <h4><i class=\"fa-solid fa-scissors\"><\/i> Spay \/ Neuter & Surgery Rules<\/h4>\n <p>Surgical procedures represent an immunologic stressor.

Full blood panels must be normal before surgery. Because FIP induces cardiac stress and anemia, a **Cardiopet proBNP test must be performed on the day of anesthesia** to verify safety.<\/p>\n <\/div>\n <div class=\"fip-grid-banner-col\">\n <h4><i class=\"fa-solid fa-syringe\"><\/i> Parasites, Vaccines & Sores<\/h4>\n <p><strong>Injection Sores:<\/strong> Developing necrotizing skin scabs or sores is common with acidic GS injections. Shave the surrounding hair with a 40 blade and apply non-prescription topical antiseptic sprays. Keep the body covered using recovery suits or baby onesies.<\/p>\n <p><strong>Vaccinations:<\/strong> Follow ISFM\/WSAVA rules. Vaccines can be administered normally if the cat is clinically stable. Consider a third booster dose after treatment ends to ensure protection.<\/p>\n <p><strong>Flea & Worm Treatments:<\/strong> Standard flea preventatives (Frontline, Revolution) are safe, but can cause temporary neurological side effects that may be confused with neurological FIP. Avoid over-the-counter brands like Hartz.

If drainage is mandatory, limit it to 1\/3 of the total volume.<\/li>\n <li><strong>Pleural (Chest) Fluid Rule:<\/strong> Fully drain thoracic fluid via ultrasound-guided thoracocentesis (chest tap) to relieve life-threatening dyspnea. Multiple taps may be required before antiviral therapy halts fluid production.

After 3 hours, the medication is safely absorbed.<\/li>\n <li><strong>Diarrhea:<\/strong> Manage with therapeutic probiotics (Fortiflora, Proviable, Pro-Pectalin) or pureed pumpkin (1-2 tsp twice daily; avoid pie fillings with onion\/garlic toxins). Low-dose Metronidazole can be used safely if prescribed by a veterinarian.<\/li>\n <li><strong>Hypothermia:<\/strong> If a cat's temperature is low, provide a hot water bottle or incubator. <em>Never place a weak, non-ambulatory cat directly on an electric heating pad due to severe hotspot burn risks.<\/em><\/li>\n <\/ul>\n <\/div>\n <\/div>\n\n <div class=\"fip-grid-banner\">\n <div class=\"fip-grid-banner-col\">\n <h4><i class=\"fa-solid fa-scissors\"><\/i> Spay \/ Neuter & Surgery Rules<\/h4>\n <p>Surgical procedures represent an immunologic stressor.

Full blood panels must be normal before surgery. Because FIP induces cardiac stress and anemia, a **Cardiopet proBNP test must be performed on the day of anesthesia** to verify safety.<\/p>\n <\/div>\n <div class=\"fip-grid-banner-col\">\n <h4><i class=\"fa-solid fa-syringe\"><\/i> Parasites, Vaccines & Sores<\/h4>\n <p><strong>Injection Sores:<\/strong> Developing necrotizing skin scabs or sores is common with acidic GS injections. Shave the surrounding hair with a 40 blade and apply non-prescription topical antiseptic sprays. Keep the body covered using recovery suits or baby onesies.<\/p>\n <p><strong>Vaccinations:<\/strong> Follow ISFM\/WSAVA rules. Vaccines can be administered normally if the cat is clinically stable. Consider a third booster dose after treatment ends to ensure protection.<\/p>\n <p><strong>Flea & Worm Treatments:<\/strong> Standard flea preventatives (Frontline, Revolution) are safe, but can cause temporary neurological side effects that may be confused with neurological FIP. Avoid over-the-counter brands like Hartz.
