This is the 3rd fit she's had in less than 3 weeks. The first two, 5 days apart, were because we'd somehow managed to miss 3 tablets in 2 weeks. The previous fit was 12 days ago. We haven't missed any tablets since then, so this fit was a bit of a shock.
She's also recovering from getting her collar caught in her mouth (luckily it was a safety collar).
We're seeing the Vet next week for her monthly B12 injection, so he can check her over and, if necessary, do some tests to make sure there is no infection interfering with the Pheno.
