Cat hydration and SubQ tracker for daily fluid history

Record oral water and SubQ fluids separately, then review daily totals, food moisture, goals, and trends beside the rest of your cat's care history.

Important note

FeliVitals is for tracking and organization. It does not decide how much water or SubQ fluid your cat needs, recommend a treatment plan, or replace veterinary advice.

Why hydration records help

Hydration care can include water from a bowl, syringe feeding, hydration supplements, wet food moisture, and SubQ fluid sessions. Keeping these records together makes it easier to see what happened each day.

This can be useful for cats with CKD, diabetes, constipation, appetite changes, urinary concerns, or any plan where your veterinarian asks you to watch fluid intake closely.

How it works in FeliVitals

  1. Log oral water. Open Hydration and add the amount, method, and optional time for each intake.
  2. Log SubQ fluids. Open SubQ Fluids separately and record each session with volume, site, and optional time.
  3. Review trends. See oral and SubQ totals together, with goal progress and recent history.

Log oral water

Record water from bowl, syringe, or hydration supplement. You can add several entries in one day and keep the time for each one.

Log SubQ fluids

Record SubQ fluid volume, site, and time. Multiple sessions can be saved for the same date when your vet plan requires it.

Review trends

Trends combines oral water and SubQ fluids, shows goal progress, and lists recent entries with their amounts and times.

Daily goals and food moisture

Set a daily hydration goal on Today using the plan agreed with your veterinarian. The summary rings show how much has been logged. The app does not prescribe a fluid amount.

In Manage Food, you can turn on food moisture hydration. When that option is active, FeliVitals uses the food portion and moisture percentage to add water from wet food to the daily hydration total.

What you can track

  • Oral water amount in ml, with a leftovers calculator for water poured minus water remaining.
  • Oral method: bowl, syringe, or hydration supplement.
  • SubQ fluid volume in ml.
  • SubQ site, such as shoulder or flank.
  • Optional time for oral and SubQ entries.
  • Multiple oral or SubQ entries on the same day.
  • Daily hydration goal and goal progress.
  • Food moisture included in hydration totals when enabled.
  • Hydration history in Premium PDF export.

Helpful for chronic cat care

Hydration records can help you prepare for vet visits because they sit beside weight, appetite, feeding, medications, litter box changes, symptoms, labs, and notes.

The app keeps the history clear. Your veterinarian should decide how to interpret it and whether your cat's fluid plan should change.

Free and Premium

Daily logging is free. Free history views cover the most recent 14 days. Premium unlocks longer history and PDF reports for your vet.

FAQ

Can I track oral water and SubQ fluids separately?

Yes. Open Hydration for oral water or SubQ Fluids for a fluid session. They use separate logging screens, and Trends shows both parts of the daily total.

Can food moisture count toward the hydration total?

Yes. Turn on food moisture hydration in Manage Food. FeliVitals can then add water from wet food to the daily total.

Does FeliVitals recommend SubQ fluid amounts?

No. FeliVitals stores the records you enter. Your veterinarian should guide fluid amount, frequency, and treatment changes.
