My cat (10 y.o.) goes through this routine every morning:
- water is available before I wake up
- I feed her a regular portion of dry food (1/3 her daily total)
- she drinks lots of water
- 5-10 mins later she throws up between 1 and 3 times
- by the time I'm done cleaning up, she is begging for food
I can alleviate this by feeding her a quarter portion, waiting an hour and then another quarter portion, then she misses a half portion cause I'm out. Then I feed her two regular portions over the evening, with no throwing up.
Occasionally she'll throw up even after a quarter portion.
This doesn't seem to come from eating wet food too fast, but rather drinking too much water after a dry breakfast (but not at other times). Is there anything I can change to stop this?
