Sorry Michelle, just seen this.
Boy was on 2 tablets a week but you need to give 3 days between and dont change the days . Boy was on Monday and thursdays but he missed one so i changed it to tuesdays and friday and if she miss one or you are not sure if she has taken it, its very important not to overdose, my vet said is better to miss than overdose.
The other thing i found out with Boy was couple of times i found the tablet a day or 2 later he used to keep it in his mouth and then spit it out, so after that i sat with him for along time to make sure he doesnt, so stay with Issey to make sure she doesnt spit it after you gone. They are so clever. Bless them. xx

To you and Issey.
