I am owned by 3 cats, one of whom is prone to hair balls. We've always been able to clear him up with the laxatone stuff though. What I have done is added groud flax seed to his diet , plenty of laxatone ( he hates it but I wrap him in a towel and force him to lick it off my finger , not fun but that's the only way with Sobe ) and I make sure he gets plenty of water. Broth or tuna juice work too, just watch the sodium content. If you have a syringe and can have him drink plenty of water that way, that would be best . Laxatone and tons of liquid seems to be key here.
As you've seen the vet, if your cat has not pooped in two days, just call the vet and tell them. Make sure they know you are broke, and ask if you can let this go another day or two over the phone.
My experience with Sobe is that it takes him two days each time before he has a poop again. However, I can't tell you if your cat is more plugged with a hair ball than Sobe usually gets.
The other thing I do is I pick grass, the tall rough kind. I have a plastic vase in my sink and that always contains fresh grass for them to chew. My cats are indoors only. This grass seems to help prevent hair balls too . Then of course I comb Sobe , Rue and Cosmo with a fine comb each day. The dogs get brushed each day too. Can you tell I'm busy with babies 24/7 ,lol.
Good luck, keep us posted, and if you are not sure, call your vet and ask for advise . Mine is very reasonable if he's already seen Sobe and knows what the problem is. And it also gives me the knowledge that if this is heading the wrong way, my vet will tell me .
